Ah man! I got to the level with 15 targets before the platforming became too difficult for me. Fun spin on the theme, really cool how we get to see the level be built component by component.
Some pointers: I noticed that the player has friction on him, which means you can move in the direction of a wall and just stay there. Also, I'd probably replace the ground check with a boxcast rather than a raycast. That way you can still jump even if you're riiight at the corner of a platform.
Thank you for the game!
