I'm not entirely sure what happened with your export, but I've never needed to include the .godot directory with my builds. I tried yours without it and it wouldn't run. Normally, it should just be the .exe and .pck files unless you embed the pck, then it normally just runs as an exe without any extra files. That aside, I think the platformer would have felt a little better if you would have used One Way collisions on the elevator platform. I didn't notice if there was any coyote time , but that might be something else to look into for future projects as people who don't play platformers as much can have an easier time navigating. The jumping/falling felt a little fast to me. After I died about 3 times, I did get the 3 skulls and reached the you win scene with the exit door.
