Spelunky 2

Spelunky 2 will make you loathe existence and question why play videogames in the first place. The level of suffering you will be inviting into your life when purchasing this game cannot be overstated. Agony has a name and it is Derek Yu.
10/10 an absolutely excellent platforming roguelite, beat Cosmic Ocean or no balls.

This game is like an abusive relationship: You either have the common sense to walk away or you let the constant suffering become your new normal.
Please help me.

This game is good, until you get wombo combo-ed by 3 different enemies and a dart trap. Then it becomes great.

I recommend this game because, even after countless hours of playing, you can still discover new things. I love that it features a vast number of bosses, yet only a small fraction of them are mandatory to defeat. At first glance, it may seem like a fairly simple game, but as you become more familiar with it, you’ll realize that it’s actually a very challenging rogue-like.
In my opinion, the multiplayer mode is much better when played online (since in local co-op, you can’t always see yourself if the host moves away from you). However, the downside is that you can't unlock new characters this way. The graphics perfectly suit this style of game, and even a low-end PC can run it smoothly.
It is absolutely worth its price. Enjoy playing Spelunky 2!

Rage - The Videogame
Spelunky 2 is a roguelike platformer that builds upon the basis of it's predecessor Spelunky HD, while improving and expanding the already proven formula in almost every way.
You start the run with 4 health, 4 ropes and 4 bombs and try to make it out alive somehow. Throughout the run you will collect lots of treasure, fight many different enemies and (hopefully) avoid all kinds of traps. The levels get more dangerous and devious the further you proceed, but you will also be able to upgrade your gear, buy new items, tame various animals and increase your health through many ways.
Throughout the run you will find shops where you can buy - or steal - various items and consumables that can increase your chances of survival. There are also many NPCs that can be encountered along the way. Some of those offer quests, others give you challenges to fulfill, some of them need to be rescued or offer to trade things with the player.
Everything you encounter is recorded in the Journal, where details about the game can be conveniently looked up at any time. Fully completing the Journal is a challenge on its own, and while it will take a very long time to fully complete, it also feels very rewarding to look into the Journal and see the 100% complete mark.
While the first game already had it's fair share of hidden levels and easter eggs, Spelunky 2 expands upon that aspect even more and often offers the player the choice between two completely different paths - each with their own dangers and their own rewards.
And just like it's predecessor, Spelunky 2 also has multiple different "endings", all of them increasingly difficult to achieve.
As you proceed through the levels you free more Spelunkers, unlocking them as playable characters in the process. You are also able to build shortcuts to deeper levels by beating previous levels multiple times and helping Mama Tunnel by bringing her the tools she needs to expand said shortcuts.
Ironically, using these shortcuts usually ends up making the game even more difficult, since you are tossed into deeper levels without the chance to upgrade your gear and health first. However, the shortcuts still are a neat tool for getting used to the later levels and learning how to avoid their dangers.
Spelunky 2 can definitely get pretty frustrating at times, since almost everything you encounter is designed to hinder, damage or even kill you in various ways. The game is know for it's creative ways of killing players, often in very unexpected or even hilarious ways. Enemies can trigger traps and explosions, some traps create chain reactions with other traps, certain enemy types will fight each other and explosive traps often end up setting off even more explosions.
However, all of these factors can also be used to the players advantage once they get familiar with them, allowing for quite some creative strategies and plays. Making progress in Spelunky 2 feels very satisfying and in my opinion easily manages to counterbalance the frustrating aspects of the game - Although you will still end up cursing the game quite so often even after hundreds of hours.
Overall, I highly recommend Spelunky 2 to any roguelike or platformer enjoyers due to the variety and depth of the game, as well as it's perfect blend between temporary frustration and long-term satisfaction.

I gave this game a fair shot because "why not", and ended up getting the full spelunky achievement, let me tell you why.
Looks simple at first but there is a lot of depth and tiny little details to make your run thru the caves as treacherous as possible: every enemy behaves differently, and a lot of them do different things depending on the circumstances, arrows bounce, there are traps hidden near similar looking tiles making them hard to notice, and there is a ton of niche interactions between items, enemies, or landmarks that might be marginally useful, or maybe explode.
But the reason I stuck with this game is simply because no other game has made me feel this angrier, or this personally accomplished. There is no other game I have felt such a high as the moment I got that final achievement because it just feels earned; You have to master the controls almost to the minute detail, learn how to deal with every trap and enemy, memorize what to look for in every stage, and improvise your way through the randomized caves to find everything the game has to offer.
And in spite of how incredibly difficult this game can be, however, my feelings of anger waned down after every run. Frustrating stuff eventually just became really funny, you know? Like a completely bullshit death that was triggered by a seemingly insignificant action you did like a minute earlier and there'd be no way you could've ever expect has made me scream like a banshee, and also had me laugh as if I was in the funniest stand-up comedy show of all time, and I was the punchline.
I have never experienced such a delicious, perfectly-balanced concoction of uncontrollable wrath, proud accomplishment, and euphoric laughter. Nowadays I cannot help but laugh like the joker at the dumbest, most ridiculous deaths of all time in my hard-earned runs, and if you really know anything about this game, then you know that every run you do will be hard-earned.
I hope this rant gives you the insight on what to expect, and help you determine whether or not you actually are like the kind of sick bastard who might enjoy this game.

Going into this game with no prior knowledge to work on and only my experiences of growing up with 2D platformers, this is the hardest game I've ever played. It makes things like Elden Ring look almost comforting by comparison.
Spelunky 2 is not afraid to just outright kill you for looking at it wrong. Love it.
