Slide from wall to wall, trying to solve a puzzle and reach the finish. The game looks like Atomix, but without atoms.

Arrow keys - movement

There are only two levels in the game right now, but their count and quality will grow.

NASM assembler is necessary for build.

You can use any of major emulators to run the game. Here's an example with QEMU:

qemu-system-i386 build/build.bin

You will need a CD/DVD disk, USB stick or even a floppy and dd. For example, if you want to burn this to USB stick which is /dev/sdc, run a following:

dd if=build/build.bin of=/dev/sdc

Then just reboot your PC and boot from the USB stick.
