First of all I love the fact that you incorporated inventory management as well :) a tie is a tie!
Now the game: it’s super cute, it’s juicy and the main loop is very enjoyable! I did encounter some bugs after a while: some items ended up in a different inventory slot instead of where I wanted to put them down and when I reached 5000 points I couldn’t put down the item from my hand (not even in the bin) even though there was free space for it; but I still enjoyed playing Monster Quest a lot. It’s rare to see something this polished in a TriJam (although you did 10x the suggested time window, but hey, good on you for riding the motivation-wave :).
