Good game, really like the idea ! I have a bit of a love hate relation with the time slow. On one hand it make the game more accessible, but trying to play at full speed was also fun (although really punishing). It felt to easy to just get surround by enemy and kill them by just swapping around. On the other hand, it make you feel like a badass, so yeah lol
Graphics were simple but good, music was well chosen (although, like people have suggested for my game, should not repeat when reloading the level) and sfx were well done and integrated.
Good Job !
