Neat concept, very creative. I loved the idea of being able to edit not just the layout of the map, but the parameters of the entities (player and platforms so far).
Building the menu at the beginning was also really clever, and set the tone for sure.
This could be a really cool and challenging puzzle platformer with some more concepts and levels. Definitely a bit too easy at the moment: setting jump height and run speed to max made some levels trivial. But there’s something special here for sure.
