This is pretty fun, and quite tricky as well, but I did manage to complete it! I like the grapple hook mechanic, it felt fun to use it to zip around, although I often zipped straight off to my death. One issue I did have is that once you narrow it down to just a few stars left, it can be really hard to find them. My first try I died when i had 2 left, and in my second run I spend most of the final minute of time just looking for the last star. The movement and physics in this game do feel a bit too complex for an NES/genesis era of game, but that's just a minor nitpick. Good job!
