I liked the power slide idea, first one of the jam I have seen use that.
I would like for the run button to be closer to WASD, G was uncomfortable as it was too far from the other buttons if you were holding up to run.
I played through about 3 times, I would have tried more but there appears to be no option to restart other than Alt-F4 the game and run the EXE again. Maybe I wasn't supposed to fall down to the gun room but I couldn't get away from them once I fell down. Maybe something easier or less confusing for a first level.
