Loving this release of the game so far, it really is starting to feel like a full-on game! And the idea of progression is quite exciting!
I did find a bug as well in the challenger event, when the player gets full and must tap their character to empty their capacity to eat again. If the auto-drain is what finishes the process of emptying one's capacity, the game locks the player's controls and doesn't allow for any matches to be made.
Anyhow, keep up the good work! I'm excited to see where you take this game next!
