Kunai

Definitely my most favorite robot game! If you liked Cavestory or Metroid I'd give this game a try!
Pros:
-Great artwork, from splash screens to the sprites. The limited palettes leaves some to the imagination! The music was lovely and enhanced the atmosphere of the environments. The characters are really cute too, I have a weakness for monitorheads hehe... The dialogue was also charming, I had few chuckles!
-The areas were fun to climb!
-Simple combat, kill to heal. Your sword is pretty much all you need to deal with enemies although the side weapons can make things easier! There's certainly some power progression as you get further along. I really appreciate that you can attack in 4 directions!
-Many things to collect! Especially hats which allow customization
-The upgrades are all optional and are surprisingly priced so that you could buy all of them by the end of the game if you are looking to 100% complete it
-The marker system was handy to keep track of old places where you could use newfound abilities! I appreciate that the markers can be set to different colors
-The call function is useful if you forget what you were supposed to do
-The bosses felt adequately challenging!
-Death is a slap on the back! You don't lose your currency or anything when dying!
Cons:
-Some areas were narrow so it became less fun to traverse since you couldn't grapple around as much
-Combat may feel clunky when trying to weave sidearms and your sword
-Lack of a fast travel system, which could make it tiresome to walk from place to place
-There are some instakill spots, but save points are plentiful enough that there isn't much of a problem
-It may take some getting used to the grapple range before it becomes second nature
-Some cutscenes play after every death once you reach a location (but at least you can skip)
-Lack of locations where chests have been opened may cause you to backtrack to the same chest more than once
-You can't select a different area of the map to look in to see its markers/chests looted
Minor Complains:
-Lack of a codex, I'd love to read more about the world and its inhabitants! If only the call function commented on more specific areas too!
-The story is a little shallow, but I love it nonetheless!
-There was a cutscene that didn't run all the way, causing my game to softlock
-There was a hat that is easily missed >:(
-One npc blows up but keeps respawning. Hmmm...
-One enemy gets stuck on a ledge and keeps making a sound
-I feel like the sidearms could be used more against enemies, perhaps some that require you to use a certain one before you can use your sword?
I hope this game gets a sequel, it was really well made! It was definitely worth the purchase!

Very epic indie game. Kind of makes me feel like a assasin spiderman

A nice compact metroidvania with an appealing art style and grappling hooks!
The only con I can think of is lack of fast travel which makes backtracking a real slog.

Kunai is one of many newer Metroidvanias to hit the indie market. It may draw comparisons to Hollow Knight, but I believe it's a bit different but still good.
Kunai is an extremely well polished game visually. All of the actions feel good and everything that moves is running through a downscaler shader to fit the pixel art style with an interesting physics feel. Some of the character designs indeed seem to be using pixel art, but the objects such as cloth and hand movements appear to be using tweening and physics quite nicely.
I would give Kunai a positive for its visuals and themeing consistency. The theme of an apocolyptic future with a tablet robot (that is extremely expressive) that acts like a 1980s kung-fu action hero when weilding his weapons is hilarious, and while the story felt arcade-like moreso than deep (the game does have an interesting premise, but the lore is not that deep) I still went away appreciating it as it stayed consistent. Over-the-top action with good comedy relief. Not a long game, but still plenty to do.
Now what's the negatives of Kunai?
-The controls "felt" off because I never seemed to get much chance to experience the full arcs that the tether effect of the Kunai gave to your movement when swinging on ceilings. As such, when I was given harder tether platforming challenges, I didn't immediately feel like I was guided in the difficulty curve to understand them. The early areas were all cramped and tiny, keeping me from seeing all of the capabilities of the Kunai until later, making me feel as if I wasn't "progressing" at mastering the Kunai tether mechanic.
As such, it will take you some time to get used to Kunai's movement mechanics
-While I loved the choice of limited color pallets in Kunai, the constant use of the dull tan color for background and some foreground elements made seeing wall spikes hard to see in my peripheral vision. I'd take damage and ask "what hit me?" Turns out it was wall spikes I did not see because they didn't have enough color contrast with the floor, spikewall, and backgroun all having the same tan color.
-I did not feel like the map layout of Kunai was that fun to traverse. There is no fast travel in the game at all (or if there was, I didn't ever run into it from beginning to end) It made trekking levels backwards an absolute pain, as I simply wanted to proceed to a new level, but got held in one place too long with no quick way to change locations. Because of this map travel issue, and coupled with map layout that didn't feel like it guided me in a certain direction when exploring, I also had no desire to obtain extra collectibles. While I loved the hats as a nice collectible, it just felt like a hassle to go collect them. The reward didn't fit the massive amount of time of traveling and attempting to find illusory walls.
-upgrades were neat, but felt too expensive to complete. Since each common enemy would only drop about 1-3 coins on death, I didn't feel like I could easily collect 300 coins for the next upgrade. I appreciated it kept it from being too easy, but it was just enough that I wish there was a reward to get that much. I wasn't able to find those challenges to earn more to be rewarded with the extra upgrades. Coupled with the hassle of exploring the map, I didn't feel the desire to go to search for challenge rooms to find more, as I felt like reward chests I'd find would only produce about 20 coins. It was easier to spam farm coins from a few of the games bigger enemies.
Overall, I believe the game is good as a metroidvania. I don't feel as if it hit the masterpiece level wholeistically, but it was still fun to play despite its weaknesses and flaws.

A solid metroidvana where your face is a tablet that makes funny and cute expressions, while the hookshot mechanic makes you feel like a deadly spiderman, and it all controls extremely well. Took me about 7 hours to complete.
Graphics are nice and the soundtrack is fucking slammin. Like a traditional metroidvania you'll get new abilities and weapons which were all a treat. Bosses are a lot of fun too as their patterns are really good and not just damage sponges.
My only gripes with the game are that yes there's places to explore and items to get, but most of them are useless hats that for some reason many indie devs love to put in their games nowadays. There's life pickups to be found to extend your health bar, but nine out of ten times I would get let down because it would be just another dumb hat. Also, the ending is...well there's hardly one at all. With all the dialogue from meeting npcs and from your chief throughout the game, the ending leaves a lot to be desired.
All in all though I enjoyed it as it's another solid game in the metroidvana genre.

The game is fun but the last boss was a bit disproportionately hard; even with all powerups maxed out I couldn't beat him and ended up just quitting. Otherwise the rest of the game was a blast and very polished.

Underappreciated little Metroidvania game that has never bored me during its 5-7 hour playthrough. Traversal is so smooth, the frequency of finding new abilities is just right, and I also liked its visuals/sound. Nothing to complain about here. If you like Metroidvania games, give this game a try. Don't expect the next Hollow Knight or Ori in terms of general quality. Nevertheless, as a Metroidvania fan, I enjoyed this game more than Bloodstained ROTN, Shantae 5, Metroid 2 remake, or Dandara.
