YOU CAN USE THIS ENGINE ANYTIME. It has collisions of all kinds, you can adjust movement jumping, and all of that. HOW TO USE You can go in and change sprites, you just have to have an idle pose, jumping pose, and falling pose. Then you have to make the hitbox the size of your character. To add more levels, you have to make a new costume on the level sprite, and whatever you draw on there will work with collisions. Going to the very right will make you switch areas on the ground sprite. Good luck making your platformer games!
When I was younger and bad at scratch, I wanted to make a platformer but couldn't find an engine to use for it, but now you can use this one! You don't have to give me credit.
