Nice game! The menu presentation is very nice, and fun how the levels have time tracked. The gameplay of making the ball move after packing terrain is quite fun too.
I think that the flow for going through levels in the campaign could use improvements, as I get pulled back to the title screen.
I also wasn’t sure how to remove the red tiles, I think it was level 4.
Also in web build, I noticed that the character will repeatedly hit a wall and not turn around. I fixed it by scrolling down the page.
