I think bench size upgrade could work in very well, especially since the gears do get pretty large. On some kind of combo effect on chaining the gears, I'll see if I can work out the math and incorporate it in! The combo effect might actually give use to smaller gears towards the end as well. Thank you for playing my game!!
I playtested the game without a cooldown and ended up just brushing continuously which felt dull. So, I added a cooldown to give players some restriction to manage instead of just being zoned out.
