I love your renders and I loved your first game
Adventures of Tara, so much so that I even pledged for a few months here and there when I could
But you are going away from what made your game so great. Even on Adventures of Tara I felt like the earlier builds were building up towards a more branching story and then eventually it became a much more kinetic story.
Perhaps you should look into trying your hands at making a branching Renpy novel, with the quality of your renders and your writing talent you should be able to make a great story! Heck, just take your first game and use that as the foundation for your Renpy!
The reason I recommend Renpy is that RPGM is better suited for exploration based games, something you cannot achieve in Renpy. A good example of this is
Claire's Quest in RPGM, it is both branching and exploration and could not be made in Renpy but perfectly suits the features of RPGM.
For example, at the start of the game you have 3 pathways to follow, if you go into one of them it takes you into a forest and you can find someone to save but interact with them too early and they die as you first should explore the other path to find apples to bring to him to save him. On one path you can encounter guards where you have dialogue options but you can bypass the guards entirely by exploring the middle path and finding a hidden way into the human encampment.... See this you cannot possibly do in Renpy but RPGM excels at creating great game worlds for the player to explore where they can replay the game and find different ways to have finished the game and you can have even multiple endings based on flags/variables you've set in your RPGM.
While Renpy can also have multiple endings you can't achieve the open world and world exploration that an RPGM can. So the school environment for example was good in Adventures of Tara but the player was never free to explore you had to go from point A to point B, it was rare you could simply go where you want and thereby change the outcome of events and such in the way that Claire's Quest and other good RPGM games do (Violated Heroine (not on F95 sadly),
Rotation Cult,
Overgrown Genesis etc...)
Instead Adventures of Tara actually played much more like how you'd expect a Renpy to play with some branching story elements but no actual game world to explore.
I would love to see your renders on a quality Renpy based game or if you really want to continue in RPGM I would love to see a more open-world design like some of the examples I have given. There are more great RPGM games out there that really let the player explore the game world but the examples given are just the ones off the top of my head at the moment.
