It does seem similar!! Great minds think alike, hahahaha!
Yeah, we toyed with the idea of screwing with the diary after a couple of levels (staining the book, stripping pages, getting a page stuck so you couldn't scroll to the next one, etc) but we thought it was hard enough... Which clearly isn't the case, XD. We understimated both the time and the ability to remember certain recipes by memory!
Fun fact, initially there was a total of 64 curses, which allowed us to make give more posible combinations for runes as a recipe (and some very dumb curse names, xD). Considering that the player had to move pages by clicking, that we wanted to have as many legible curses in each page as possible and a limited amount of assets for icons we could use (that we could have modified to have more, but time keeps running!), we cut more than half of that list and left it as it stands today...
More feedback to add to our "things to consider for release" list, :D!
Thanks for the kind review, really appreciate all the feedback, :D!
Cheers!
