You couldn't get out of the basement to collect all four suncubes? The basement door closes on you (should be AFTER you put all four suncubes on the table) to make sure you solve the first 4 block pillar and get a clue before you try the second... hmm, lemme check into it.
And RE: the hint cards. They are readable whenever you want... press TAB. There are instructions!! : )
Glad you liked it anyway, despite some undue extra effort... thanks!
