The design of the game through the level design and maps is very interesting. The different colors, obstacles, and usage of enemies works well. I like the improvements made between exercise 5 and 6 to make the game experience more smooth and balanced for the player. The different and unique level designs also give the game good replay-ability. One critique I have is to ensure that player feedback is absolutely clear, and the best way I find to portray that is with a good combination of visual and sound effects.
