-Tell the player about the menu button at the start. "The menu button near your nose" is too cryptic and the little chevron is easy to miss.
-Add the option to have the music loop.
-I don't see an inventory anywhere. If you let go of the mouse button before reading what an item does you're SOL.
-There doesn't seem to be any way to restart the game other than deleting the cookie.
-Backtracking is a nightmare with all the arbitrary one-way paths and jumping back and forth between pages. Needs a map, or at the very least "tight" needs to be colored to stand out better.
-Tooltips for player cards during combat are blurry.
-The brain scrambler is really RNG heavy since you have to use the singular hole card to be able to hurt it at all. I thought it was one of those fights you were meant to lose at first. Can enemies steal the hole card?
-The tooltip for the card you get from the brain scrambler goes outside the edge of the screen.
Some misspellings/typos/grammar mistakes I noticed:
P 54: automata --> automaton
P 55: much hits --> many hits; attacks --> attack(s); stallmate --> stalemate
P 57: missing "an" before "overly"; don't panic --> not panic
P 39: on --> one
P 70: phenomenon --> phenomena
P 72 : Probably the phenomenon has --> The phenomenon has probably
P 67: Missing comma in last sentence.
P 76: a form --> the form
There were some missing articles I noticed earlier, but again, I can't restart the game to double check.
