thank you for the suggestions. may i ask why do you want detonator to be a ui button, and what is the auto-mining tool?
Detonator as a UI button would be useful if connecting multiple quarries with one line so you don't have to travel back to the original quarry where the detonator would be.
Auto-mining tool could be anything you think would be appropriate, could be just a guy with a pick-axe crushing rocks. Just a way to earn passive income.
I was also thinking how blast radius is sort of over powered but it's not really a problem as an incremental, however, it could be interesting if instead of just one bomb type, you could use different bombs. Different bombs have different radius and power. Then you could introduce hazards. This is starting to get into the territory of an entirely different game though.
If we keep with the theme of the current game though, widening the field, or sort of changing the environment could potentially keep moving the incremental forward.
After you reach a certain threshold, change the rocks to be mountains, then from mountains to planets, then planets to star systems, then star systems to galaxies, galaxies to universes. It's just an idea.
If you want to keep it very simple, just make it infinitely incremental but have the rock sprites have lives/layers.
Also, the auto miner could be something as simple as an "Auto-layer" that lays the bombs and detonates them for you, think of a little bomberman walking around dropping bombs on the field that blow up after a period of time, You could spend money to upgrade his bombs, drop speed, move speed, safety equipment (if he hits himself he gets knocked out for a period of time.)
I mean, a lot of these suggestions kind of feel like they should just be a different game or a sequel, because the one here is pretty good as a proof of concept but sort of plateaus as an incremental game where money becomes a struggle to gain as exponential growth is impossible and dimishing returns on upgrades forces a soft cap.
