Love the character art and all the little props! The mechanic is also really creative. I love when a simple mechanic like this completely changes the way you move through the game.
It felt a little clunky at times because the bat would sometimes drop me immediately, even though I was still holding the key. I would’ve loved to reach the end, but that issue made it pretty difficult. I also missed having some music to accompany the player, jaja.
Other than that, great job!
