I haven't pushed to github (Will do this soon), but I believe that i've fixed the issue (also, by wanna fix this bug I meant I want to fix this bug, (but would def also appreciate help if ur interested, the mechanics of this game ended up being a bit more complex than I initially envisioned lol))
No problem. I am currently on the third level I think and my laptop fan ramps up, so I closed the tab and it stopped. Also, how can I delete e.g. transistors again?
