Great game! The character felt good to control and I like the concept of having to lower your stats to make coins, it adds an extra layer of strategy to the game. The boss battles felt a little grindy, especially if you lose to a boss you potentially lose all the progress you made. I think this just requires a little balancing and playtesting. I would also suggest adding a little more platforming into it as well, the tutorial felt a little disconnected from the rest of the game. Overall I think it's a really solid game all around and I had fun playing it! Great work!
