I just hope he doesn't rush it.
Au Pair for instance, feels like a buggy mess on Ren'Py because the developer rushed to move it. Part of this games charm is how high quality it feels compared to the rest of RPGMaker games. Learning an entire engine in 3 weeks just doesn't seem doable whilst mainting the original polish/quality he had. Maybe he should look for a coder, there will be a plethora that see the clear monetary potential in his game and might want in on the action from the get go.
I think this is a mistake and this developers attitude is just giving me too many red flags. So far he has release exactly one demo, an extremely good demo admittedly, but still, it's a 0.01 demo. Now he's already talking about remaking it in another engine, talking about how he doesn't have far more patreons and talking about how RPGMaker won't handle his "10,000 images".
It's way to impulsive for my liking.
Let's just hope this is a good idea, because this really had a fuck load of potential.
