I like the idea, and up to around 10k it's a lot of fun, but after that it feels like it's so easy to loose track of the character. He's dark, the background's dark, even the blocks are dark, especially when the blocks are low it's difficult to see were they start or end. I think some outlines on blocks or character, or colors to stylize them, would give them a more defined appearance and make it easier to time jumps. The gameplay is fun, the music addictive, but the color's bland. Keep it going!
