It took me a silly amount of time to realize I should use the bombs on the cracked walls.
It was fun and very fast paced. Kinda gave boomer shooter vibes.
Only thing I'd say is, maybe it's a bit harsh that the bombs kill you in one hit.
But it did make the Boss fight even more intense. As is usually the case for tough Bosses with a lot of health; circle, strafe, chip away and don't get greedy.
