First I played this game in FireFox with very low fps and lags. But win version looking good. I like halloween theme in game, original idea and hardcore gameplay. Good game for prototype, interesting concept. I think with level design (level select screen, scores/time and more visual effects like a screens tremor) and more mechanics like ghosts (from mario/pacman) this game will be awesome for HTML5 game portals. Good luck with this game!
