it feels great to play. i think making it easy to get OP and then balancing until it's hard enough is a good approach to crafting a game around a "runs and upgrades" mechanic, so you're in a good place.
hover to fire is nice. a later upgrade that works with just the direction of the cursor from the center, and lets it be any distance might be a nice QOL addition (although maybe only on/outside the circle, to prevent players from rapidly circling around the origin hmm).
Thanks for making and sharing this!

I'm able to leave Thicketon in the Mac build of 3.1. The reroll indicator seems to still be layed out relative to the window dimensions rather than the viewport (screenshot , ^1) but that doesn't affect playability.
