Thank you! In my opinion, the biggest problems were camera being too close/characters being too big, and the jank that comes with high speed physics. Also, giving the character a giant ponytail wasn't the smartest of moves... hair physics is already hard, combined with rocket speeds it's just jank city.
I want to revisit this idea someday, but I have a million ideas for small games currently, so I'm not sure If I'll get it to soon.
