At first, I thought that the game's art style felt very "busy". But as I played through some of the levels, it started to grow on me. The vibrant colors really meshed together in a flattering way. It had a nice, straight forward goal. I like the simplistic character designs, the controls work beautifully, & the dynamics of level navigation is incredibly fun. Although, some stages start to get rather repetitive, including a bit more variety in their construct would have helped. The background music and little sound effects, however, were defiantly the icing on the cake.
Overall, a well-made and entertaining game. A bit more refining of the lines in the earlier stages would have been nice. It seemed a little too sloppy but I understand that you may have wanted to go with that loose feel. Regardless, great job!
