Aahhhh that's what you meant. It wasnt clear that you meant the current version from your original post. Rather it seemed to be about the completed game...
I believe earlier posts have implied that once the next version goes live the current version (2.1) will go free2play. I don't know for certain.
However heres something of note. Above it has an Important note:
'If you choose to pay for early access here (on Itch.io), please note that it will only be valid for 1 year or a minimum of 3 updates, whichever is longer. So, if you purchase early access now, you'll receive updates for the next year or at least 3 major updates if they take longer than a year. After this period, a new page will be created, and you would need to renew your early access. This system is designed to be fair for those supporting on Patreon, who contribute monthly to receive the same benefits.'
I think the part I Bolded may be important here. RebootLove is intending to create a brand new site for the game each year or 3 updates.
Now I'm just theorizing but part of that may be so he can do the free version a little differently too.
I just checked and Genex Love Part 1 is still only free up to version 0.3.5, you must pay $10 to get the 0.9.97 version.
So my theory is that maybe the Dev wants to max out his profits by having a free version of Genex Love 2 and then a paid version that includes more content, like he did with part 1. He would then repeat this for each new website to bring in greater profits.
Or he might make the version on this website free once he makes the next one. It's impossible for me to tell with out using Telepathy or Precognition. I cant risk my secret Identity so I cant do that, sorry.
