I just finished World 1, which means the game is roughly 50-60% done. The difficult half is over anyhow, most of the programming is done it's all about design now. With any luck progress should be faster.
I'm still looking for music for the game so if you want to check out the songs or make a suggestion you're welcome to it. Songs Post. I added a five stars system to replace the question marks. Makes the page more interesting.
