Pretty cute game! For some reason, I really wanted to be able to run with the boy character using the B key (it reminds me of Red from Pokémon). At first, it was a bit confusing to realize that I had picked up the shovel. I only noticed it after opening the inventory. I initially thought I had to press something for it to appear in the icon. Also, I’m not sure how to use the Tome. I assigned it to slot 5 and pressed it multiple times until the game broke and showed a “null function return” error. It’s possible I accidentally pressed 6 or 7 as well, that might help you reproduce the issue.
