I died at round 72.
Pretty good game!
Some tips for improvement:
1. allow the player to raise the money limit to 300$ or higher. Once I got to round 40+, I couldn't really buy anything from the shop anymore otherwise I would die (would lose the multiplier from money balls)
2. Shop items aren't balanced. I was seeing high value tile items in early rounds and then super low value items in the later rounds
3. Gameplay feels repetitive in higher rounds, can you add the option to speed up time so that I can skip the animations?
