Thank you for the kind words, Im glad you enjoyed it!!
The stairs are realtime 3D, I dont have much experience with pre-rendering 3D objects ðŸ˜
When the player moves, the stairs are simply rotated and moved up. Once they are outside the camera's view, they are despawned and a new stair is spawned underneath, so it doesn't overload the game :) It actually took me quiet some time to get it to work right, since the stair-animation is done through script as well. That is an incredibly good point though, another frame for the stairs and player animation would make it look a lot better, thank you for the feedback!
