I am the developer of the game. I think of it as four stars

This game definitely makes the logic part of your brain work! At first I wasn't sure how to transform from square to diamond. I used the D button to switch to the diamond and the left mouse button to move vertically. Regarding UI I found that the two arrow buttons at the top were unnecessary because I could just click within the area of my player to swap shapes. Thanks for placing the pause button because breaks help. It was interesting that at first I was more concerned with my green score than I became more concerned with my red mistakes. I ended up leaving a score of green 533 and red 130. As for the art it was clean and overall easy on the eyes. I do appreciate giving it depth by making the background blurred and it helped to focus on the foreground. The ukulele was a nice touch but at one point I actually heard breathing/sighing/child unit making noise so I would probably edit that part out. So far this is one of the top favorites I have reviewed as of yet!
