That's good. A common criticism so far has been the jumps and getting stuck, so its nice to hear someone actually made it to the end haha. And yeah, I loved the music transition into the last area. It just feel like a solid mood for the area.
In regards to polish, ohhhh yeah. I can list a bunch of things off the top of my head. Quite a few wouldn't have taken that much effort and time, but when the end of a jam hits, you just get lazy and chalk it up to the nature of game jams.
I could definitely see another metroidvania with Tommy in the future once my art gets better haha
