Really interesting idea to generalize the minesweeper, and the implementation is nice as well.
I felt that the developer smoked something funny around lvl 108, it's getting pretty nasty there.
Anyway, thanks for the game :)
I played until the middle of level 3 (region), and until that point, the most efficient tactics was always the 4 generators around the (not necessarily) newest burner, I tried many other versions, even the water thing suxx. The progress slowed down pretty much which is really evil together with an active tab needed (at least it doesn't see if I'm using another browser). On the science point it fails pretty much as well
- the nuclear is pretty much thermonuclear (also the fusion, but in an other way)
- how much power can you sell to the world? :-o
By the way, the end cannot be reached without cheating. I upgraded the forge as much as possible, and after this, trashed more than 50k gems to get one of the best pickaxes, which is an Incredible ULTIMATE PICK +19 with quite high power and 2474% Q. This is enough (on maxed upgrade) to beat Hellstone lv. 1181. The only thing I miss, is the high active power, which could give another factor of 1000, a few ten levels. That's all...
The lv. 2237 is not the real end. I't because of money oveflow, so it can be done on previous levels also. I suggest to limit the money value. Also, the loading suxx around level ~2220.
