ok, i noticed 2 bugs in this game:
1. during the last boss fight, my ramei double triggered, so the final boss's action bar did not move. i abused the crap out of this to deal enough dmg to him before he overheated like mad
2. sometimes, if a weapon breaks, fix equipment doesn't actually fix it. the buff icon stay permanently on your character, and the debuff is removed during the second encounter.
also, i finished the whole game without limit breaker 3 (holy crap that took forever. the final boss shattered his own armor 3 times and took 2 actions every time i took one =.=)
the level before the boss fight took a lot of tower management out of me (ended with about 3 anti-air and a single ground). the last fight in comparison was disappointing (only needed orbital strike once). also, HP boost was never really needed if dmg was rushed like mad.
