Excellent game. I've had it in my Steam Wishlist and will purchase it when it becomes available. However, I do have a suggestion that I think would raise this "A" game to an "A+++".
As it is currently, if you continue to corrupt the MC in the "game world/mind space" you see more and more changes to the MC in the real world...both in her appearance and behavior. That is really well done and for many, the main reason to play the game. If, on the other hand, you do your best as a player to avoid corrupting the MC, you rarely see any events at all in the real world.
I want to suggest to the creator(s) that it would be an even better game if we saw real life events that result from not corrupting the MC. For example, if the player manages to progress the "in game" story, defeating enemies, etc., while minimizing corruption, we could see the bad guys fail in real life as they fail in the game world. We might even actually see them becoming better humans because of the positive influence of the MC.
Just as corrupting the MC in the mind space/game world effects her in a negative way in the real world, have her success in the game world without being corrupted have a positive effect on the bad guys. I realize that would be a lot more work, but even just as a concept I think it would be really cool.
