I’m no survival connoisseur, and the other comments have covered a lot of what I was going to say.
I played the bomb-elf first and got all the way to the end on the first try without getting a single health upgrade. It got pretty exciting when a horde of enemies started showing up at once, I’m surprised I even managed it.
I died playing as the witch about 1/3 of the way, I really couldn’t tell what was doing damage most of the time. I think the little bullets the eyeball enemies shoot should be a lot more visible because they seem to get lost among the particles from your own character and I think that’s what killed me.
With some appropriate SFX I’d say it’s pretty close to feature complete already, pretty good.
