The creators of Radiant are also working on other projects - 4 that I am aware of, counting the support they provide to other creators for other VNs.
While I want quicker Radiant updates, they owe their Patreons their best effort for the other projects and for the VNs they already committed to making.
If they broke all their commitments to other Patreons and creators, then why would anyone believe that they would not do the same with Radiant.
As the old saying goes - the seats in the peanut gallery are cheap - or, in F95 - free.
Complain all you want about not getting your free stuff fast enough.
I'll enjoy some of the hundreds of other VNs here on F95 (and support those I like enough to keep playing) while I wait patiently for the next update of Radiant (and many other quality VNs).
Why not spend less time complaining here and more time enjoying some of the other VNs on F95.
If you find one you like enough, consider supporting it via Patreon, Subscribestar or whichever method the creator asks for support.
Hardware, in game music, assets and voice acting are not free so whichever VN you choose will benefit from your monetary support.
