Really interesting game, I was trying to reach the boss but eventually it crashed:
LowLevelFatalError [File:D:\build\++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp] [Line: 452]
Illegal call to StaticFindObjectFast() while garbage collecting!
0x00007fff62857374 KERNEL32.DLL!UnknownFunction []
Crash in runnable thread Background Worker #3
It was kind of running poorly when a bunch of enemies were on screen and I had 4 of the spawners on one level and they kept spawning mud golems so maybe that caused it. Although it crashed in the next level.It was pretty difficult at the start, I had to restart a few times until I got going but it was interesting enough to keep me playing which is good. I feel like the starting deck sucks. There are a bunch of modifiers and types of damage which I never got to use because all the starting cards do the same thing and you can't really build a strategy until you've cleared a decent amount of rooms.
Also when enemies are below you it gets a bit annoying because you have to reposition the camera before you can target them even if you know where you need to aim. Or maybe scrolling with the RMB just feels unnatural to me.
Great work so far, the gameplay is really fun
