Dang i forgot about the try again screen? Its in portuguese, because i just carried over some menus i had alheady made for another game, i guess i missed one :(.
Could you explain what problem you were having with the ability? My guess is you got the teleport one (they're randomly assygned at the start of the level) and wasnt in range of any enemy. It still gives you a boost, so you dont just waste it, but its very faint.
And the killing enemies is on me, i should've put some diferent sounds for when you hit them. Actually, every time you hit them, with your movement, it deals damage, and the damage is based on your speed and spinning velocity.
