Amusing game, little buggy.
Knockback is still a killer - get hit by spikes once and you can forget most levels, bit OP. Same deal with seahorses that can avoid you by going through walls: if an AI can charge you from behind a wall then you should be able to do the same to it. Managed to complete one level after dieing and landing my tombstone on the end-level marker.
Awesome story / level quotes, liked the boss - hardish until you learn its pattern but then uber easy.
