I guess I won't be the first to use this tweak, but my game will be called "Unlimited space".

Here is a link to a playable pre-pre-alpha version:

For the moment, you can just move in the infinity of space, but you can go wherever you want. No limits !

You will play as a galactic taxi driver. Now it's time to add some customers.
