Simple but fun little game. The controls are tight and responsive, movement isn't too slow or too fast. It gets hard but not overly frustrating. It never feels like the game's fault you lost and you always feel like you can do better. Music is cool but gets a bit repetitive. I was confused at first by the green blocks 'cause I thought 'Hey, green=health', and they were sideways so I thought I could jump on them. I guess I should read instructions more carefully when it says to pick up hearts for health. The game could use some more detail, like if the background was more detailed. Although I guess that would get a bit distracting. Also, you could add leaderboards through the NG API.
