The graphics are nice and the mood is cool, gameplay is challenging and fun, even though pixel perfect player collisions are a bit too unforgiving (even using a collider slightly smaller than the whole player would go a long way towards making the game more playable and less stressful).
The animation when the player hits an enemy is strange, looks to be kinda glitchy, I don't know. Could use a lives counter, too.
The main issue I have is it crashes very often. Tried with the latest FCEUX, after a few deaths what happens is shown in the attached snapshot.
