Colorclash
This is an unofficial port of the game Colorclash (a.k.a. Avalanche) by Revival Studios to Game Boy Color. Clear the incoming blocks by shooting them with the correct color. The game ends when the blocks reach the beam at the bottom of the screen.
Most of the graphics were taken and adapted from the 2002 J2ME version of Colorclash by Karma Studios. The music (composed by Faried Verheul) is from various unreleased Game Boy Color projects by Karma Studios.
Everything you see here was written in 100% pure assembly - no GB Studio here!

fantastic graphics, and writing it in asm is hard core!
It is a little hard to work out what is happening on the high score name entry, maybe putting some up and down arrows above and below the current letter might help the player track where they are editing
Great work
I really like the concept of this puzzle game! And it's beautifully designed!
Thanks for the game :)
