What a great aesthetic! Everything about the audio and visuals was really on point, even the voice acting which is surprising for a jam game. The waves and upgrades made for a nice flow, even if the mechanics were pretty simple. While the betting mechanic doesn't really come through, I like where you guys were going with it - splitting the players attention between fighting enemies and engaging with the board mechanic seems like a good direction to go. What if you could only defeat enemies on a certain number? Or staying on certain numbers presented some sort of hazard?
Overall, a great submission!
