Crashing Blocks
Crashing Blocks is a falling blocks game that boots right from the CD, without even loading an operating system first. It is text-based, but still shows colored blocks pretty nicely. The current version speeds up after every line cleared, rather than every 10 lines, as is standard. Download crashingblocks-0.1.2.tar.gz
Download crashingblocks-0.1.2.iso and burn it to CD-ROM to try booting it from the disk
