WASD to move. To use the engine, just remix the project or backpack the code. Edit the costume in the Wrld sprite to make your map.t. If you edit the size of the player, be sure the hitboxes are still correct. In the Setup sprite, change the Tick broadcast to Tick Platform to make a Platformer.
All by me. You don't need to ask to use, just please give me credit in your game.
