Neat concept and good execution; albeit on the more basic side, this game definitely has more room to grow. A few things I think might've been neat for this game would be that each shape is matched with a type of rhythm (then, its less of a watch when the red shape appears on the screen and more focused on the timing), additionally, a combination of the 3 shapes as later levels (with each shape bound to a different key) combining those rhythms could create an interesting experience. It might also be more visually interactive if each shape had its own way of needing to match (what I mean by this is maybe rather than having the circle shrink, have the circle go left to right, thus creating more variety for the eyes). I had no issues with level 1 and 3, though the tempo of level 2 could probably use some tweaking.
