The game here on itch.io will probably be just a standalone project, that I will (probably) not develop any further. This was ment as a little side project for the charity #TeamWater Jam.
If you have seen the video, you probably know that I have big plans for the concept behind this game, which will be pretty time consuming. So the Steam Version will definetly be paid - though as a lot of people in my community do not have very deep pockets, I will only ask a fair price with a possible discount at the start. Game might cost 5-10$, possible discount would probably bring it to 5$ so people can actually afford it.
I am working solo, so I am unsure how long this will take - but I am planning on making a cool, affordable experience for everyone.
Hope that clears it up a little :)
