Amazing game easy 5/5 the upgrade system is not the best i have seen but upgrades are upgrades. A tip for the last/all levels with more then 1 CPU, they DONT focus on you. They will go for the cells of weakest strength, so if you are sending 100% of units to new cells yes it will seem like you are getting focus as the CPUs will target your cells however if u send 50% at a time and dont let your cells drop below 15-20 units in each they will not "focus" on you and will attack each other. Tis dosent mean you wont get attacked by any but you wont b getting "focused" on by all 3 at the same time.
This could be an awsome game its a rilly nice idea, but you made it way too hard to get money, the only way is to pick up coins which are almost impossible to get with the speed you move in the begining. if u make so you get money based on how deep you go into the earth or simply add ALOT more coins in the begining
amazing game. BEST top down shooter ive played sence Enigmata,one thing i can think that would be a nice addition is small rewards from completing medals. 5/5
