Good game! Really like the art style and the scene transitions!
Feedback:
-way to turn down volume. really loud when first loading it up
-SFX for button clicks
Looks like there are some bugs to squash:
Level 11) Colliders not working on some of the blocks linked to the button- you fall through. If this intentional, you need a visual indicator
Level 12) invisible colliders that prevent you from jumping- something got mixed up and so the buttons are not working with colliders. Also, level 12 is not passable with the current spike hitboxes.
