this is a really nice game! love the art, music, and gameplay. i agree with Cracked Walnut, refilling the gum takes a bit too long, and i'd prefer just a little more hang time on the jump (but that would probably require rebuilding the levels to adjust for that).
i found a little bug! i bubbled too close to the ceiling and decided to see if i could squeeze above it... i guess not! i got stuck in the ceiling
