A real fun time! The physics of the heart platform confused me for a bit but once I got the hang of it some of those jumps ended up being really, really satisfying! (Though I think it would be extra fun if we could have a little more control over where the heart ends up, too!) I think some of the levels might be a little bit long for deaths to reset you at the beginning, especially in those first two levels when you're getting used to the mechanics, but it was satisfying to get better at it. Cute art, too! Those bats are the bane of my existence, haha. The puzzle at the end with the three switches was fun, and I feel like that kind of puzzle could make for a really fun focus in the full game, especially while managing the platforming and action. Great work and thanks for sharing! :)
