I liked the writing overall. It was good how you largely explain the world through inference or events, like the spawn point thing. There's a good explanation for Bludge to be worried, for how spawn points work, and for why Bludge can't rescue Astra immediately.
While the game definitely runs on horny logic, I still like how there's a sensible reason for the demon setting things up the way he did. Does enough to kick-start the entire process, then doesn't waste further direct time with it. It feels sensible within the logic of the world, which I really appreciate in writing.
Overall, I think you have the core of something pretty good here, and I definitely would like more if you'd like to move forward with it.
Edit: I'm not entirely sure RPGMaker is the right tool for this though, especially if you're having a lot of trouble wrestling with it. So far at least, the RPGMaker format doesn't seem to be contributing much to the overall experience.
