I am pretty sure you have no background in game development (and software development in general) just based of your profile picture
, just kidding, actually based on your comment, because someone with that background will NOT make such comment.
Please give the developer the chance and opportunity to "crawl before he can stand up, walk before he can run" with
Ren'Py. Although he can already "fly" with
RPGM but
Ren'Py is something totally different, it is like comparing
Mandarin language with
Swahili language. I don't even play the game or familiar with the developer but I applaude his bold decision and effort. I understand your predicament because you are only seeing things in the short term but if you broaden your horizon to long term, you might see things differently. Cheers.
