Really neat idea, I'm currently stuck on level 8. Initially I thought it was going to be a pretty mediocre affair but when we get introduced to the teleport things go up a notch.
I did find that the difficulty ramped up when timing became important at level 7, might want to ease that in a bit more, especially with how the level restarts and you can get continually killed after just a second or so as you try and figure what to do. But I managed it so might be just me. Style wise, really nice, maybe add some more character with some idles when the player is standing still.
Overall nice and polished presentation too. Will come back later and try and get past 8, feels like there could be a lot of neat puzzling with this teleport thingamybob.
