Game speed changes with the mouse speed ! that's smart :D
very fun game :3 reminds me of "Super Hot" :3
unfortunately i got stuck in level 2 because after killing the enemies i tried to build my way up to portal but it didn't let me build, no idea why >.<
when i jumped on the enemy head and died the jump sound effect triggered infinitely D:
overall, a very well smart and unique game <3, well done ! :3
