So far I have not planned any sales related matters...After all, I make games all the time
Currently I am planning to put the free ver game on Steam and other platforms.
But that's just because I need to gather some feedback on the game.
If everyone responds well, maybe I will consider selling the full version in the future.
I would be very grateful if you could sponsor me for a long time...after all, I don’t have many resources at the moment.
But this is not mandatory, you can definitely pay just once.
Currently, the only way to obtain the full version is through Patreon's "Pioneer" tier.
You only need to sponsor "once" to get permanent access to future updated archives.
I think this is similar to EA sales on Steam.
