Really liked it, when we get varables this will be so much easier.
I didn't see where secret applies, found a hole in the invisable walls though (seventh level)
You found the Invisible Portal!
Hahaha I'm kidding. Thanks for pointing it out. And thank you for stopping by :)
The unexplained mechanics were supposed to be the secret: logic gates. I intended it to be a mystery to the uninitiated, though I may have been too transparent with my choice of block symbols. Plus the tagline and one of the tags give it away.
The fact it was empty (I looked everywhere inside it) and there wasn't corners for the invisible walls around I got out of, made me think it wasn't on purpose.
The clean black and white colors add to the computer/logic theme, if it look more like it was from fantasy (runes and portals instead of buttons and gates) it might have been harder to figure out, it's great how it is now though.
