Free license
Free as in “free speech”, not as in “free beer”
Since December 25, 2023, Superfluous Returnz has been an entirely free video game: its engine Sosage is published under the MIT license (on Framagit and Github), and its assets (game data, images, music, etc.) are released under the Creative Commons By Sa license.
You can thus download the game free of charge (see below), modify it and share it as you wish. Nevertheless, please remember one thing: developing, testing, drawing, animating, writing, composing music, recording, communicating... all these represent a substantial amount of work that can only be viable if it is paid for in some way.
The game took more than 3 years to create, and its total cost is estimated at €45,000. To this day, earnings from sales on the various platforms and donations represent €5,510, reimbursing only 12% of the work involved.
If you believe that a game like Superfluous Returnz should not be produced at a loss and that it should be possible to create viably other free video games of this kind in the future, you can buy the game on the platform of your choice or make a donation:

You can also download the assets to compile the game
yourself. Note that they are provided in a compressed format in order
to get the best performance: if you wish to access the data in
conventional formats (PNG, OGG, etc.), you'll need to decompress them
with the SCAP utility, provided with the Sosage engine.
