I don't intend to sell the full game for money. Definitely not even *possible* either with the amount of copyrighted/licensed stuff I yoinked (you can see a brief overview in the credits file). Anyways, thanks for playing! I'll respond to a few choice things:
Backside & Finale: Backside is pretty easy to find as soon as you're feeling even a speck explorative, but I've seen people *actually* miss Finale, even solving Graduation first before they knew about it. I'll probably try to err on the side of more obvious in the full version.
Picking Favorites: This puzzle is constructed of a lot of "micropuzzles" for each individual color, weaved together. It's definitely a bit of a tangle, but I figured one that, at this point, the player probably knew how to untangle anyway.
Confusign: This puzzle was actually sort of a risk in my eyes, because this technically teaches you about the Underflow mechanic used in World 11, but could be easily confused as implying "doors with negative copies do not have their locks changed" unless you hovered your mouse over the door and saw the negative lock count. And, honestly, this one's mechanic is as simple as doing the thing to the thing anyway, so I'm not sure too much is lost from outright explaining it. I'll give it another look though. I like to be very blunt about certain mechanic introduction puzzles.
Lens of Truth / Imaginary Doors: The only reason I dump the lens on you the way I do is because I didn't want players to have a button that made the doors look all weird in the earlygame and then think it could be applied to the early puzzles somehow. (In fact, that's why it exists at all.) I *do* intend to add spiffier graphics for all the Imaginary Doors to fully 1-1 match the special lock graphics for Real Doors. Honestly, the graphics of these mechanics in particular is jank as all hell.
Prose: First off, "adore" is a door pun, and you will NOT be hitting me for it. I will catch your fists and judo throw you into a Combo Door whose locks consist of your every last fear and regret. Jokes aside, I see what you mean by the prose dropping off (I distinctly remember the ones which mention that the narrator is running out of new things to talk about), I'll probably be redoing a few choice ones both to be less awkward as well as to retcon a few details.
Again, thanks for playing!
