Interesting idea, kind of let down by frustrating controls... when I clicked on a rune I expected that rune to change, but it seemed that a random other rune would change instead. I initially thought that clicking a rune changed the runes on either side, which would have been fine as it introduces a puzzle element, but that also didn't seem to be the case? Either way, after clicking about for a while I finally managed to get a combination that was accepted but wasn't the best for the scenario so I was booted back to the menu... The game also needs some serious polishing, and some music!
