The opening/voice acting was really cool! I have no clue what any of the items did and I got soft locked in the color flash puzzle.
You should be able to leave the puzzle with Esc, as for items, in the inventory (toggled with Q) you can see info on all of them.
I pressed "esc" I was locked into it. Thanks for telling me about the "Q" inventory
Hmm, weird, I'll look into it later.
