Journey of a Roach is a rather short adventure game which is pretty easily completable in one sitting (there's even an achievement to speedrun it in 18 minutes which only took me two tries.) It uses silent storytelling with simple cutscenes telling the simple and rather nonsensical story. You play a cockroach in an inhabited underground area populated by other bugs. The game is very strange with a lot of the things that happen not making a whole lot of sense to me but it all fits pretty well with the bug civilization theme.
The game is unique in two aspects: First you use WASD to move around rather than the mouse like most adventure games, and second, being a bug, you can climb on walls. There are restrictions however since the camera is in a fixed position so you can't climb on the foreground or background walls. The camera rotates to follow you which can be disorienting but it works well for the most part. There are a few places in the game where you will get stuck trying to climb on things but it's easy to get out.
I find that the weirdness of this game doesn't lend itself well to puzzle solving, but the game tries to give you hints through thought bubbles when you inspect objects. I find it still ends up being on the obscure side which is unfortunate.
I also had strange performance problems in the last section of the game with the game stuttering badly despite my computer having far more power than the game needs. I posted on the community hub about the problem so hopefully the developers can fix it, but I haven't heard back at this point.
Overall I find this game hard to recommend. It's rather expensive for the length of the game and the lack of much of a story. There's a lot of better adventure games out there, and even for $5 more I'd recommend them over this.
