Excellent little game! I had fun throughout! Clean, polished end result.
The hitboxes in particular were perfect. There was never a doubt about whether or not I was touching something. And I love that the tiles allow you to 'know' with some certainty that you are out of harm's way.
I also agree that the level design could be more intentional, but given the time limitations of the jam, I am extremely impressed.
I think if you give it a little TLC and maybe a few more mechanics you could have a great game on your hands.
Thanks!
