I feel that when you [GET THE BANANA] its a bit overpowered, since you take no damage and are fully healed. Maybe if you take damage it ends or it just doesn't heal. My first try I got 260,000 because I [GOT THE BANANA] like 5+ times.
As for other ideas, I would make the berdley statue give more [Kromer], and make the dog thing's attacks be able to be hit and removed, or be able to hit it directly.
