i take it it ends when you restart the power system? The game itself was good and the collisions themself worked well (seriously, most other entries i've tried you clip through walls, get stuck in floors, etc) with two somewhat major issues, jumping is like i'm wearing rocket boots on the surface of the sun i go up so fast and come back down so fast, makes it REALLY hard to control the jump. the other is the LADDERS, it's nearly random whether you sucessfully make it all the way up or down a ladder since you seem to simply lose gravity while on them. Other than that most of the rest is superb, especially the lighting effects.
I like how the guy doesnt instantly kill you too, lol, you can just totally brofist him as you walk by and keep on your business, i tried to die and the screen didnt even start to get staticy for a good 10-15 seconds. also, no, you cannot jump on his head to kill him like a goomba :/ I like how you did the effect of him only moving when not in the light also.
