Interesting game. I beat it (got overflow) and wishlisted.
I think the main problem is too much clicking. Merging got better after getting the collider, but the generator still takes a ton of clicking. The minigame took quite a lot of clicking too, I think it would be good if we have autoclicking upgrades.
The auto input of collider isn't fast enough to keep up after getting all the collider speed upgrades.
