Thanks for the feedback. Makes sense to me tbh I was kind of just inspired by some Quake 2 levels and trying to mess around in that style I didn't know what to do for the theme exactly. The combat isn't that great in general because I was using the built in CopperCube stuff.
You have to find all 3 Cyphers for the end to open up on the first level, the beam that lifts you up was just added in for fun lol but it does seem important for no reason haha. The charges are actually usable in the last level if you can get to it which is supposed to be kind of like a hidden reward. Also if you hold shift to run before you jump you will go higher and not get stuck but then again I'm not sure what hole you mean really I did find a few places where you can just escape the bounds of the map already but didn't have enough time to fix them. I assume you mean the hole with the red light you should be able to jump out of that holding shift. Anyways thanks for actually taking the time to play it and glad you liked the art style I'm an artist so that's mostly what I'm good at still working on the mechanics side :)
