Nice job on this game. It's not really my type of game but I can appreciate the effort you've put into it. So well done.
A few things I picked up:
On some screens the text doesn't wrap, like on this one:
Also you can type past the end of the textbox on the doodle search page (if you put in really long words). Not really serious, but maybe you can limit how many characters the player can enter.
Finally, maybe you can find a way to integrate the 'txt Notes' directly into the game somehow. It took me some time to figure out there was information I needed outside of the game executable.
Overall though, nice work.
