The initial concept is fun, the simple visuals work well to distinguish the colored blocks and I like the look of the little character!
I expected the game to progress after the 4th level with puzzles that use the new scale ability. I thought I messed up by going back and stopped playing because level 3 was so long and tedious and I didn't want to do it again.
I only realised that was intended when I read the "How does your game fit the theme?" Is the idea that you go back to the old levels bigger and move stuff around for fun? It would have been cool if the scaleability was needed in those levels to progress as it feels like the game doesn't use the theme otherwise.
Really well done making it tho I enjoyed playing it!
