I don't know if it was supposed to happen, but I got to a point where I only got cyan blocks, no matter how many times I restarted it. Had to refresh the page to get normal blocks again.
Great game tho!
Reviews for "Portal Stacker"
I enjoyed it, really entertaining hybrid of tower blocks and tetris, I could definitely see it as a phone app/game.
Nice game, at first i thought i was suposed to make it as small as possible, just like a tetris game....
