First try! I pretty much ignored sniper and heal once I saw I got the same damage from the rifle. (Already forgot what the arrows were Assault Mode)
Shotgun was used to hit the 100 HPs and I basically cheesed the hole to kill the boss.
It definitely had "Last Spell" vibes, but with Dead Space. And the modes definitely made it pretty strategic. More variety and story with more levels would be nice post-jam.
