I know I'm late to the party, but damn, guys, this is amazing. Blew my expectations out of the water. Hard to believe it was made during a game jam. Well done!
If you don't mind, I've got a couple questions:
1. Did you use tilemaps here?
2. What did you use to create the wavy relfection at the bottom? Shader magic?
P.S.: Just checked your Twitter, says you've been a game dev. for only two years. Wow. I'm envious :)
