Thanks for the feedback again! Really appreciate it, I'll keep these things in mind as development continues.
Also, if you haven't checked the Steam demo out yet (just released it last week), we did finally get a unique boss theme in :).
Although in that version, the melee base damage is even higher haha. I ended up changing the ranged modifiers like multishot to be multipliers (so they stack exponentially), and it ended up being much stronger than melee lategame. Things definitely still need some work though haha.
