(oh hey, I rated this but forgot to comment.) this is one of the entries that make me wish it was a full game. I can imagine more levels and items that you can only get in one world or the other, maybe even enemies that start infiltrating the safe world. there’s a lot of potential here.
as it is it’s pretty fun, it gets too easy once you play it a couple times but that’s understandable for a game jam. I like the sound design too. nice work :-)
