That's a very innovative concept. Really like it.
It's pretty difficult for my taste. Played now for a while, but reached max. level 5 (with still over 2 minutes left^^)
That the tiles disappear was at the beginning a bit hard to control. But it's actually a pretty smart game mechanic to ensure players walk around, and do not just "camp". And as soon as you can handle it and notice, that enemies bring them back, it's actually pretty fun.
The perks in general are pretty cool and very well balanced.
There was actually just one little problem with the jump: Seemed that it sometimes did not work (even when I've got it)... not sure, or it was maybe just hard to distinguish of running upwards.
But all in all very nice polished and fun game.
