I am not that good at the game, but really fun and interesting concept. From what I tried well done for a game jam game. It definitely has a GB feel to it and an interesting use of "Old Gold"
I did find a couple of bugs though.
1. The waves seem to just disappear sometimes even when the meter isn't at 0.
2. If you interact with a sign while riding a wave then the wave sprites will be glitched.
