This is really cool. There's so much attention to detail, love it!
The animations are all meticulously crafted, the money raining down from the chest, the enemies spawning, the confetti when clearing a room, everything is so slick!!
The exp system feels really good, I didn't play before the update but I really like the progression feeling and the extra upgrade choice from leveling up.
I love the ammo system with a bar that fills back up instead of reloading or god forbid limited ammo! It's just so much nicer not to have to worry <3
I wish there was a pause menu, but once a room is cleared I guess there's not really any need for one :)
Do you plan on uploading desktop builds of this?
P.S I think you left all the debug hotkeys in, maybe that's on purpose? I know the number keys are since you mentioned them in the devlog, but the P key, the O key etc do stuff too :p
