Very polished. Managing the furnace is fun twist to the proven survivor-type gameplay loop.
I think theres a bit too much of a focus on ranged / projectile enemies. There are a lot of things flying at you at any time, and whether three white pixels are a bone or a bolt isn't easy tell.
Also, some of those hit boxes... don't know feel a bit dodgy, got squashed a lot without an enemy anywhere near me.
I would have loved to see a tronger commitment to a theme. Mini guns and magic wands, giant mantis's and animated snow men? Eh~ I'd say, stick to one direction.
All in all:👍
Propably gonna come back to this for a couple more rounds.
