Out of the Blue

This is a Gameboy game made in gb-studio that supposedly has link cable support, in which the two players are trying to free "The Creature" from the world that he is trapped in. Like a real Gameboy game, almost none of this lore is mentioned in the game :) Both players have 5 different items they can find, and the goal is to send the items that they find to the other player so they can complete puzzles in their world with them. This game plays more like an escape room then anything else, but it was made more as a proof of concept than as an actual game.
