SumBlocks is a game I made back in the end of 2004. I made a basic version without even any music, and then I didn’t do anything with the game after that. Some people said it was too difficult, which is true.
This week I started working on the game again, though! This time I added music (from The Mod Archive) and there is now a tutorial and an easy mode! Also there are some minor graphical changes.
Anyway, for more info, go to the game’s webpage!
