I like the retro first-person dungeon crawler experience with the retro textures and everything.
The looking around sensitivity I wish was a little higher or customizable as I had to whip my mouse in a direction a couple times to get a nice turn going.
Enemies also one-shotting you isn't super fun since they take 4 hits to die. After a few runs though I got the back up and hit them technique down pretty good.?
If you wanna go for a fast paced action crawler one shotting for both enemies and players, plus bumping up movement speed and look sensitivity some would go a long way.
