The upgrades should be that you get more energy in less time instead of making the time that they stay longer. Now I have to wait the whole for my cells to be used up.
Also when one of the cells is almost drained I would just like to be able to put a new one over instead of having to wait until its fully drained or sell it.
I also would like to see somewhere how much heat the cells give when I mouse over them, now I have to crunch the numbers myself when I have 3 reflectors next to a cell.
I also think the capacitors are a bit expensive when just starting out.
Maybe a sell all button for when I want to start with a new strategy. I was also thinking: if I have a basic heat vent and place and advanced heat vent on top of it, it should automatically sell it and place the automatic there, as if it is an upgrade.
Great game, 5/5. The only thing I hate is how those 2X stars are displayed, I cant see the difference between the green and the blue ones anymore when they have the 2X star on them.
I'll play with shrinking their size or making them more transparent
