There really needs to be a massive upgrade to autosell/capacitors for then endgame. Single protiums rapidly build up more generation than I could possibly sell even if I could have every til as ultimate capacitor.
The money counter breaks if you leave the game running for a while and get sextiillions while your best thing generates quadrillions. If you spend below quintillions the counter will zero until you get back up.
So the second boss instantly shits out 4 battleship factories while I barely have time to make one and some basic economy/fighter defense. Not sure how that's even possible to beat.
Night time, do a gekkyu under void aura.
Also, upgrade all Soul Tempest skills and charging will be faster and will have a huge blast to damage and repel enemies.
Artifacts don't drop nearly enough to matter. I had enough for dagger strike, flying dagger and 8 left over when I maxed everything else. At least dagger strike is cheap and amazing for getting your specials out.
"Gun canon" seems really shitty. Every point in it just adds an extra spread bullet to the very beginning of a burst when you almost never fire less than a full bar at a time.
Plasma cannons seem massively overpowered. There doesn't seem to be much point in building anything else when they punch right through armor while hitting flying units and causing splash damage with a good rate of fire.
Supercarriers are hilariously overpowered, especially with physics labs. Any mission that starts with at least 2250 can be won by making opening with a starport spamming super carriers, with possible exception of the level 100 duel.
