What graphics card + OS are you running? That sounds like a whole new set of problems.

As soon as I went down the slope in the beginning I couldn't see anything. After flailing around a bit I found myself in a lighted area and killed a few enemies. Fell through the ground a few times too.

I've had this reported a couple of times now, and I get it on my own laptop as well. The HD4000 drivers don't support OpenGL 3.3 which is what I'm currently using. I do have a couple of ideas for working around this (Using GL3.0 functions or forcing GL_ES) to get the game to work on these chips, but it won't be ready in time for this demo day.

I'm getting graphical issues on my Intel HD4000 graphics under Linux, probably resulting from these failed shader compiles.

I played this and found it enjoyable. There's some weird (shadow?) rendering issues in parts of the level, and holes in the terrain, but I'm sure you're already aware of this. I tried to jump on top of the wall thing across from that high up area with the extra ammo... but I couldn't do it. Not sure if it's possible, but I've always liked that sort of platforming challenge in FPS games. Also please add a murder room filled with enemies for testing purposes.

Pretty impressive for one of the few 3D agdg games!
