def rack your brains challenging exercise, used the majority of my brain cells for this lol.
i think it would be good to show a mark on the level card we finish, at the very least to show visible progress on which level(s) far we’ve passed and a highlighted version (like just with shadow, slightly brightened up color or something) upon hovering if it’s possible. also could use a sound effect on the unlocked gate, have a dash option (esp helpful for the long, roundabout routes of some levels) and a smoother/reduced abrasive sound for the pushed box because if we use arrow keyboard to push it continously, makes like a loud, layered repetitive noise.
