sorry for late replythere is always just the right amount of biomass to buy upgrades in each level
check for aliens and other things around the map to get more biomass
yeah the exact amount, but good thing in my opinion would be if on each level there would be a little biomass more, 1 or 2 for example
Yeah i'll try do thatI did experiment with that idea, as in the intro level there is an alien bullet you can pick up which gives you 1 extra biomass
