Cool GBA-style graphics. I like the world you've built here and the tasks the NPCs give you.
A few suggestions:
-Needs music and SFX.
-The corn maze is a bit too much.
-The J button is a bit inconvenient when my other hand is on the arrow keys. I would recommend adding WASD as an alternative to the arrow keys, and/or changing J to Space.
-Consider adding a control to dash or run in order to move faster.
