I love this game so much. You pulled it off perfectly in my opinion. Every level felt like a fresh concept because while the core concept was the same, the actual manipulation changed (scaling the blocks, scaling the players, scaling the freaking spikes, scaling the camera view while also morphing half the level!?). What an absolutely creative take this is!
The funniest part was that my only major complaint was going to be that when the shapes scaled, they kind of clipped into each other and slipped off. But then you basically exploited that ‘bug’ into a feature in level 15 XD. I really enjoyed the unique ideas in “Pit rider” and “Pythagorean theorem”. On that note, the puzzle titles were genuinely helpful in addition to being witty.
Coming to minor gripes; I think the simplistic graphics worked in your favor, but maybe a little more detail like faces on the circle would add more flair to the game. Some SFX would also be nice when you scale. Basically, just a little more polish would be neat. I have no other feedback! It really felt like you knew what worked, and you used it to its fullest extent. Awesome job!
