“half hour”? I need just 15-20 minutes. No more than 10 to beat another 2 campaing levels (dont have fuel for more), the rest is to find what useless trash I want to sacrifice to get 5 boost daily task and to get 2 arena wins, and maybe also buy a box or two
but right, 15 fuel is too little amount. If one of missions I beat is boss one (and I am clearing hard/insane missions now), I dont have fuel for another one. I remember, in WarMetal: Tyrant you unlocked permanent energy upgrades as you achieved new levels, I think could add here something like that, increasing max energy as you level up.
