First a technical note on navigating the world. Right now you've got the navigation arrow keys unlocked, so I can flip through cards in order without doing things properly, so you may want to fix that. If you put this in your deck-wide script it'll make it disable navigation when the deck is locked
on navigate x do if !deck.locked send navigate[x] end endOn a semirelated note, I saw that the menu section of the screen is often left blank with the art, so you may be interested to know that if you press "m" to see it and draw there when you're in a drawing mode.
I found moving around with the arrow buttons pretty obvious, but it took me a while to find the hotspot that got me to the first puzzle through the bars. Like I was going through several times trying to find where my cursor changed but not seeing it. Not sure if that's part of the challenge or you want to make it more obvious.
I think these kinds of puzzles may not quite click with my brain haha, like I was hitting all the hints and even then I was finding myself trial and erroring through a bit. I'm hoping others can give some feedback here because I think this kind of puzzle may not quite be what works in my brain, but since I did eventually get through with the hints that might mean it's balanced OK.
I have to agree with Screwtapello that the number on the wall thing was a bit odd, maybe there's another way to word that or hint at that where you don't go "but wait why can't I look"?
The shape fitting puzzle did go well with my brain once I realised "oh the filled in squares are free squares, not holes". I wonder if there's a way of doing this where you can drag and rotate the pieces instead of just clicking squares to change colour, might need some more advanced coding but the rect module in the draggable example deck could help here.
I am definitely excited to see the ending because ooh that cliffhanger
