I've recently been toying with a new idea for a game, and I wanted to see if it made sense to anyone here. So, here it goes. Most of the names in here are tentative, and some may not make it into the final game.
The setup for the game is classic: the player awakes to find that they have washed up on the shores of a beautiful island called Isla Bonita with amazing architecture, sparkling fountains, statues, gardens, the works. The player is welcomed into the city on the island, called Luxonia, given the grand tour and a large apartment to stay in (the people here haven't had visitors in a while). The place is perfect, and it seems, devoid of crime and wrongdoing.
However, throughout the city, (if they're observant) the player should notice strange manholes with black hats painted on them. Later, a young boy wearing a similar black hat wakes the player in their apartment in the middle of the night (no need to lock doors on an island with no crime, right?). The boy says something about how the player walked through Luxonia, as though they had never seen a place like it. If that's the case, then maybe they can see that not everything is right on Isla Bonita.
This is a game filled with secret tunnels, and a very deep backstory. I'm really excited about it!
