I'm glad you found the idea interesting even though you went through some jank, I'm gonna try and adress your complaints right now, mainly camera and mouse cursor and the fire too. I've just been so used to replaying the same levels over and over it doesnt cross my mind unfortunately
and yes, physics are really hard to get right for a rookie gamedev like me, there's a lot of values that go into how everything moves and its really time consuming to get it "just right" especially when those values need to change later to accomidate a new mechanic
and there are actually a couple mechanics that didn't make it into todays build
anyway your feedback was really valuable, more valuable than feedback i can give so thank you.
