This is my fixed version of @ExpiredMilk2's A platform with problems. I added my platforming engine, made a few tweaks to the level and here it is! I didn't spend any time on graphics or music, as that is not what he/she was asking: he/she was asking for the engine, not the art.
The first project on my test account! Love, fav and follow me and my main: @ChessGrandmaster10! I make fun, unique games on both accounts! ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Thanks to @ExpiredMilk2 for the original project. I hope I helped you!
