The game is good, definitely did very well in the level design. Each level has a unique order of progress. I would say the movement is a little too difficult and unreactive for this type of game with small corridors and sharp turns. it also made it hard to get away from enemies which made it feel a bit unfair. If the layout was changed a bit to favor open spaces or diagonal movement so that your momentum isn't completely stopped by the invisible wall you couldn't see. Other than that I only had one major issue and that was on the second level. I couldn't figure out how to get back to the starting door without jumping and even then I couldn't tell if that's what you were supposed to do or not. Level design was still very good though!
