Pretty good. Got this record on killbox.
I think the reflect upgrade and the time boost drops are new, both good addition.
Didn't care much for bathrooms because it's too bright. Game room was cool.
There still isn't a tell for when the combo is running out, some UI element like the combo meter getting redder or a circle around the cursor would be useful.
I'd like being able to shoot all weapons right after a reload by holding LMB, some weapons can do that but not all.
Do the spawners reset or slow down when the crossbow guys arrive? There's always a lull in the fight when that happens and it messes up my combo.
Some indicator that the spawners are about to activate would be good so that the player doesn't have to guess when there are no enemies on screen.
Some gameplay considerations:
I got that record by stacking up 4 greater buckshots. Stacking a single weapon is ideal because you can quickly buff it to insane levels (it was like almost +40 when I died) and you can buy shop upgrades for it faster.
The greater buckshot felt like the best because it does crowd control, no self damage, great single target damage and can be fired blindly to try and kill off-screen enemies to keep the combo going.
I'm not saying you should nerf it but maybe you should add a "style" meter that rewards the player with points for mixing up their weapons.
Very fun overall.
