Thanks for the feedback!
I tried to do varying enemies by color but I kinda ran out of time so scrapped it
The max out city power was intentional as I wanted players to have an extra layer of strategy when collecting power capsules and collliding with enemies to lose power stored, although I realize now that it was not obvious in any way so I'll tweak that XD
Thanks for pointing out the speedup bug too, didn't even realize that even existed XD
I'll fix that in next updates after the jam
Thanks and hope you play the future updates!
