I give this game thumbs up because I appreciate the idea of it, and want to support developers trying to do something different. Yet, it was a mixed experience overall. My biggest issues were;
1)The trailer is quite misleading. The game has pretty gloomy and dark atmosphere, not comical as the trailer was. So my initial feeling was disappointment, because game was nothing that the trailer made it look to be. But eventually, the atmosphere of the game stands on its own. Just be prepared that the game is not as funny as the trailer.
2)I didnt feel that the procedural system adds anything to the game. The environments are made randomly for each playthrough, but there is not enough variery in the landscape patterns to make any worthwhile differences via procedural system. Its the same barren lands, and having the same trees in little different places doesnt really enchant the gameplay. The game is not a roguelike either. When you die (and you die very easily), you dont start the game from a 0, but just load a checkpoint. This imho kills the point of randomly generated world, since you dont need to really adapt into new world every time you play it, like you would do in Binding of Isaac, Rogue Legacy, Spelunky, etc. In this game, I kept thinking that it would be much better, if the open world was well planned solid world full of unique situations, instead of a procedural world.
3)Sneaking is too hard, and too punishing. The distances in the game are very very long, and most of the gametime you will be running from point A to B, without really sneaking. But when you reach a point where you "must" sneak, often its better just to shoot the enemy who is in your way, and run away as fast as you can. Doing proper sneaking can take a lot, lot of time, and getting spotted by enemy when too near to them is almost 100% death to you, which will mean a lot and lot of time wasted due to rare checkpoints. If you run and gun instead, you will lose only a 1-2 minutes of your time (most spent on running), instead of 10-20 minutes you would spend trying to sneak properly.
Overall I was somewhat disappointed with the game, but liked the idea and style of it enough, that I wish the developers move into a new interesting and unique projects soon. Apparently this game is getting a multiplayer someday, but IMHO its waste of time of the devs, and they should just make a new game instead. For time being, I can still recommend this game to the people who are fascinated by the idea, even though it has its share of problems.
