How about making white cubes be effected by all "Dmg vs Element" Upgrades, since white is made out of all colors. It would also give a bit more use to purify which is useless right now.
Well, you fixed the hellstone prices, but they are still kinda bad.
The cost to buy and absorb hellstones is
10 for blues, 19 for greens and 31 for reds, which makes the green ones the most effective, then blue and then reds. it should be balanced in a way, that makes the red ones the most effective to buy/absorb.
Could you add an upgrade for mission which implements auto-restart into the filter, making it filter and then run all of the filtered out, runnable missions in a row, if it fails, it moves on, if it doesnt fit with the BP, it moves on
Baldurans, there is a bug with conveyors on fast, they dont seem to be faster, and for me, they always fill up and my factory doesnt have a full production.
Maybe add a link for people, that find it too hard to reach tier 3/4

you should make a "restart at wave ******" or a "no projectile" graphic setting. just some tips for the game, the restart thing would be needed, as it would make farming easier and the no proj. too!
