Ad Infernum

Ad Infernum...what can I say? It's a rather fun and short immersive sim experience. As you can tell by my hours, I managed to finish in 2.6 hours dying only twice on normal difficulty. I'll give pros and cons as normal and you can be the judge on whether or not you wanna try out this fun game.
Pros:
1. Exploring is encouraged. I've found tons of ammo and health items scattered about thanks to me exploring a lot. Running around and killing enemies is important to exploration too as they drop crystals that give you crafting material.
2. Immersion elements are really good. I've jumped through windows to get to different parts of the gas station, created short cuts, skipped puzzles to get specific items early, manually hid under tables to keep stealth and have thrown bricks at enemies to save time and ammo. The immersive elements fit well and make it possible to speed run (this may be the case since there is a completion time that ties in with certain rewards I won't mention for spoiler reasons).
3. New game plus on any difficulty. Wanna test your metal on different difficulties with all your gear like in dead space, go ahead, all the difficulties have a level of challenge that can spice things up even on NG+, plus it adds a lot more replay value.
4. Inventory elements that make items that seem useless play a big part. I picked up a rusty wrench that did more damage than the hammer, problem is, it swung slower due to the rust. Low and behold I used a bottle of acid on the wrench and it removed the rust, making it swing faster again. The items and inventory encourage experimentation that I quite like.
5. Simple puzzles that are fun and challenging. The puzzles don't waste time with their difficulty but also don't feel too easy, they have you thinking outside the box for a bit and can give you a good amount of satisfaction.
Cons: (nothing much since this is a simple and short game)
1. The ending sequence has a small bug, I was choosing the alternate option and I guess it bugged out due to me switching weapons. just a minor fix is needed.
As of this review, the game is on sale from its normal price of ten dollars and its well worth the price, I recommend that if you do try this game out is to go in blind and with an open mind.

Absolutely fantastic survival horror. Good amount of unlocks for NG+ for replaying or challenging higher difficulties. Some really good music and some pretty creepy horror on your first run. Genuinely really surprised me, absolutely worth the price tag. I spent about 4 hrs playing through the game once normally, taking my time to explore, and one quick ng+ run to snag the other ending.
Can definitely recommend this game if you're looking for a fun survival horror game with combat, resource management, and an upgrade system with some variety. Hammer and P19 my beloved.

Most of the game plays similarly to Granny or the early part of Resident Evil 7. Combat is very limited as you are instead hunted by an unkillable zombie while trapped in a small map for most of the game. It really didn't appeal to me but the aesthetic of the game is amazing, as is its soundtrack, voice acting, and atmosphere. What an underappreciated gem.

a short game, only 1 and a half to 2 and a half hours long (first playthrough of course), but an interesting look into how you'd make an immersive sim styled game such as prey into a shorter format. Has some challenges you can try do for added play time, but most people will only get 2-5 hours of playtime out of it at most.
If the playtime doesn't scare you off, its quite enjoyable, though i wish more was done with the nerve system as I found it didn't impact the game much, especially after the first playthrough.
Can recommend, but only if the length doesn't bother you much.

Short but well-made ImSim horror game. The atmosphere and sound is great, while graphic is acceptable (it's has its own charm though). Interestingly, this game also has lots of replayability due to its Extra and New game+ (you keep weapon upgrade level and purchased powerup to next run).

Story is bit weak in my opinion, and the feel and music choice of the last section of the game is a bit out of place (but I welcome it, since it feel like a relief after the horror part of the game).

Overall 8/10. Worth your time and money.

A decent little horror game with an immersive sim design for it. I don't consider "immersive sim" a genre, more so a design philosophy. It's not quite as fleshed out (pun intended) as Amnesia: The Bunker or System Shock. I believe it's more an issue with the game having too much for so little. The entire map is pretty small with only a few branching paths. Not sure why the game has crafting, customization, health/nerve upgrades, and so many items/weapons for a game that can be beaten in about 3 hours. It feels like a game that was supposed to be bigger. There's only 3 enemy types and very little story to get invested in. It certainly has a bizarre ending(s). I enjoyed the sanity system, but it could have been better implemented. Food, pills, medkits are way too plentiful for nerve to ever be a concern. It doesn't help that you can easily craft these items. The low sanity effect is way too intense. I couldn't see at all and that's a problem when just being in the general vicinity of an enemy lowers your nerve even if you're not even aware they're around. Combat and movement are very clunky. There's no impact to melee weapons and animations are stiff. Enemy designs are largely forgettable. The graphics aren't great, but that's fine. The atmosphere is there and the game scared me at several points. The final gauntlet at the end was just out of place and the eye enemies that spawn around you just undercut the stealth focus of the previous portion of the game by forcing combat. I found Ad Infernum still refreshing nonetheless mainly because it's an actual game. Too many horror games that are linear walking sims with cheap jumpscares and dull "you went crazy and killed your family" plotlines. I see the vision with this game. I just wish it was developed more or more focused on its strengths instead of just having a bunch of mechanics that are underutilized. For example, acid used for dissolving rust is rarely used or needed. I recommend the game for its low price. (6/10)

Cool bite-sized immersive sim!
I really liked the setting, the haunted gas station in the desert, it's pretty eerie and perfect. There's just enough exploration in the different areas to make it so that you can engage that loot goblin part of your brain.
Overall I had fun with it and I can seriously see myself going back to 100% the game, there's still some fun stuff left to see, and multiple endings, too!
The dev is also very responsive, too. I had a bug with my PC where the game would crash intermittently, and I was able to reach out to the developer and send over my crash dumps. He was able to resolve my bug and I can confirm after more playtime that the game is more stable than ever!
