First thing I thought of when I read the tile and a brief description of the game, which described it as a delivery guy in the year 2500 was Futurama. Theirs no website as he seems to be using social media and the only one I can see is the Twitter feed https://twitter.com/MoonmenGames
the game is set in our solar system and you get around the different planets by jumpgate as you can see from the vids. you will also be able to get out of the ship and walk around the city’s or use your jetpack.
From the vids the game looks to be going well but it may just be a number of different levels at the moment, but it looks like it will be worth keeping an eye on it progression. Check his YouTube channel as their are a number of vids exploring different aspects of the game.
