The gameplay is really great, with level design, that ramps up a bit too fast for my taste, to match. My only complain that area would be to press jump again to activate the mid-air jump, instead of just doing immediatly after slashing.
The game is a bit buggy. Hitting ceiling spikes of from the top, which makes the first jump in the 2nd stage extremely tight, or the game randomly locking up for a few seconds after dying.
Needs some polish, but otherwise good :>
