I am trying to replicate Celeste's engine. 60 fps: turbowarp.org/991359266?fps=60 60 fps and true size (use fullscreen addon): turbowarp.org/991359266?fps=60&size=320x180 Controls: Left-Right arrows: move Down arrow: duck Z: climb (not implemented) X: dash (not implemented) C: jump As of now: Collision with solids works. All of the existing physics only do work for a flat world. - beta 1
