Dash-ball? Yeah, exactly that or something, a Unity game of some sort. I didn't set out to make it, it just happened while I was testing some things...
Jump - X
Move - Left Arrow, Right Arrow
Dash - Direction + X
e.g Left + X - dash left
Right + Up - dash up towards right diagonally
Restart Level - Backspace
Dash and Jump reset when you land on a block.
