Albeit simple in concept, this was a very fun playthrough indeed!
I quite adore the design choices, visually the game looks very pleasing, with bright colors and polished graphics, the art-style is very cute too, the clean looks really adds to the experience, and renders the game enjoyable even in usually monotone situations,
I really liked the game concept, it was very creative and well executed, the controls work well and the motions solid, I really enjoyed the puzzles ad had no problems in my play session ( maybe I am good at this xD ) so we can positively say the gameplay loop is very satisfying, and did not stale at all on my session, thus we can conclude this formula has a lot of potential, and obviously the game has a sense of polish and feedback that makes it feel great to play,
overall this is a very solid entry indeed, we can conclude that this is fun!
I see a lot of potential to expand this concept, and I would totally play this in a more streamlined, expanded package, 9/10 great work especially for such a shot time-frame, truly excellent!
