This one genuinely caught me off guard!
A platformer where you create the platforms is a pretty tired concept, but the ability to go through platforms (and lasers) and the ledge-climbing mechanics made this super interesting, and trying to use less platforms than intended was really fun! If you ever expand on this concept, maybe adding a par system wouldn't hurt? It gives the player another goal to aim towards besides just beating the level, forcing them to think about and engage with the game more critically.
Had a great time playing this, awesome job ^^
