A great idea and you've managed to implement a lot of features. The feedback sometimes seems a bit too random (e.g. there should be an item called "4243") and sometimes the feedback is not updated when it has been fixed. I'm also not sure if there is a win condition or if I am just too bad to reach it ^^
Overall, it's a fun and interesting game, just needs a bit of polish (like 99% of game jam games) :)
