Being Slovak, I was pretty excited when seeing this game on the store page, as the game was made by Slovak developers. Unfortunatelly, in its current state, this game is not far from being unplayable. I´ll start with the good, because there´s not much. The art style is pretty appealing. The almost retro-style graphics are pleasing to the eye. The second positive being the music. It does fit the creepy and depressing setting of the game. Unfortunately, those are all the positives I´ve been able to salvage from this, so now I´ll move on to the negatives. The first, but least problematic would be the lack of enemy variety. There are only 2 enemy types, but it´s more like 1 enemy type, because they behave exactly the same. One is a zombie soldier with a stahlhelm, the other a zombie with an officer´s cap. Both behave exactly the same and die from 1 bullet to the head. The second problem would be in the guns. I´ve been able to find 4 in the 2 levels of this game that I´ve played. Problem is, there´s not much point in using the remaining 3, because the starter pistol does the job just as well. Now, we move on to the bigger problems. A really jarring one is the wrong description of…

where to start...this game has a ton of potential. but right now, it is a buggy mess. I was getting necrovision vibes initially, and I love that game. And this game's combat does feel pretty good. It's snappy and the enemies feel great to shoot. That's about all it has going for it right now. When you die, you spawn back at a campfire. the enemies also spawn there ,behind you,& are literally already in mid-swing attacking you when spawning in sometimes. And you die in like 3-4 hits because you don't revive with full HP. I had no idea where to go. This was worsened by the map glitching out/disappearing/falling through it. so I pretty much just gave up because it was a buggy, frustrating slog

This is a very hesitant yes. First and foremost I don't like the use of generative AI, especially since this is something you pay for. I only noticed it after I paid or I probably wouldn't have got it. If this aspect is just a placeholder, I understand, but there's better options that would actually represent the game. If cost is the issue I'd literally be willing to do work for free. If it's not and it's an active choice, then I don't think it should be supported at all if a developer is willing to cut corners on art and voice acting. Despite that I still had some fun with the idea, and the atmosphere is really top notch. I love the retro style of it, I think that works well for the setting. With some polishing, tuning, refining, and TLC this could be really excellent.
