This is pretty fun! though it is annoying when you think a letter can be created this way, but then it can't.
side note: how do you create a y? i can only make N's and J's.
Yeah, sometimes they are simpler than you think or need to be done a specific way.
*hint* How would you make a "Y" combining two other letters?
Also the recipes you've unlocked are in the journal, even if you made one accidentally in another level it would be there.
You can also make Y by combining 3 letters. Guess which. ;)
3 i's?
y = i + i + i
