Ok, here are some minor tips for a sequel. FOLLOW THE LUMINES FORMULA! I loved how the music got louder, but maybe if you had a symphony track or maybe have done something with this one... basically make it so that the higher your score, the longer you live, the more complex the music would get. Same with the background. The flat colored background equaled suck! The further you progress, & the longer you last the more complex the background. Make the pieces themselves change color as well. Have a scrolly message drop down that says, NEXT LEVEL! COLLECT PINK, AVOID WHITE! Change up the shapes of the pieces as you progress as well. The further you get, the more they blend in with the background. How hard would it be if your crescendo became a glossy glass crescendo? Oh & if your really want to make it hard take a cue from Katamari Demacy, & make the crescendo get larger as you collect! That'd make it really hard! Fun game as it is right now, though! If you make a sequal & follow so much as half of my suggestions you're guaranteed front page!
