Very very good. I didn't get to play much, unlock the door go to the basement, but then wandering aimlessly. :-D But I did enjoy the graphics (zelda influences am I right, I had some too :-D) and music. I would prefer instead zx keys to the keypad for d-pad left and buttons right setup for the GB soul, but ok, it's just personal preference just for this jam. Excellent work.

You really need to follow the dialogue to know what you have to do next. After going down in the basement you need to pick up the note near the dead cultist body. It will tell you where to go next.
The game has controller support so you can use a game controller to play the game for a more nostalgic feel. I also used the most common set up for gameboy emulators.
