A very cute entry! Loved the town you set up. Unfortunately, I'm pretty dense so I couldn't figure out the fishing mechanic. But everything else feels like it's something straight out of a gameboy game. ^^

It's too bad you couldn't experience the gameplay. For info, in the description there is an explanation of how it works: Essentially you are a player moving in a room (d-pad) and you have to find a zone, but all of that is hidden, the only thing you see is your gauge: periodically a white bar giving you the distance to the zone (not the moving bar, the 1px high one that fades). Fishing up artefacts then unlocks the two other gameplay loops
