Unfortunately the game kept freezing for me whenever I fell of a platform and it would never recover. Also, the sucking would break a little sometimes and I'd be stuck sucking for no particular reason until I reinitiate it.
I understand you used external assets for the animations and what-not, which I feel helped make the jump feel so nice, but the platforming still felt pretty nice all around. Nice choice of music. The star trail was a cool look.
Cool retro kirby game.
