The game is good and i was able to finish it, but it slowed down on a few of the levels (especially pseudo snake), which made it very hard and frustrating to get a large amount of coins. Also, the jumping mechanic may need a little work. I found myself sometimes able to control the height of my jump to avoid low objects while other time, I could not. Also, jumps from underneath a block is a pain sometimes because I just hit my head and fall.
Still, I like the game and the coin collecting aspect. I wanted to turn everything in the level into coins.
