Nah, when I went back in my godot project, apparently it is another kind of bug.... :))))) I knew I should have taken the 2 days of bugfixin seriously but currently, I don't think I understand where the bug would be coming from on my own wacky scripts. Thanks for pointing it out tho!
As for the second level, I hope you'd at least could reach the first button to unlock the next step of the "puzzle"? The coin placements were deliberately placed at trickier spots and I was hoping I didn't make it too hard. I appreciate you trying it out though!
