ShiftBlock

This is the game made using allegro.js library. I couldn't make any better graphics because I was ill.

The rules and controls are explained at the start screen of the game.

I hope moving and rotating game board fits the theme well.

EDIT: There is a problem because of spacebar scrolling the whole Ludum Dare website. I don't have an idea how to fix it, because I left keyboard handling to the allegro.js library instead of writing it for myself. It is better to use web link provided below, at least for now. It uses the same link as iframe used by LD website.
