Fun short little game. The missing half star is for lack of content and too much trial and error for the medals. I realize the conciseness was probably intentional, but I just felt like there could have been more to it. It was definitely a unique concept and direction, but I left the game feeling what was the point - little skill or strategy was involved. Lastly, it seems the only reason to play this game is for the medals and I'm not trying to sound inconsiderate or distasteful. I just felt like the game lacked an experience or overall purpose other than the medals. Not just that, but the medals had no clear instruction. I understand that medals are meant to be earned, but the amount of trial and error created what I felt to be unnecessary playtime. Don't get me wrong, they were rather easy to figure out and obtain, however that process was definitely more about repetition and less about perseverance. Nonetheless, it seems that you were successful in obtaining what you set out to do and met all of your intentions and for that I give you a high score. Besides, it was short, sweet, and to the point! (no pun intended)
