I would ask some more about MOSI:
1) Is there a way to set variables on start game before first steps?
2) Can I make minor NSFW games with nude content on Mosi? Or maybe isn't so good idea?!
3) Is there a way to add new rooms without deleting old locations? I just forgot to add some more rooms.
4) How to get Ending or Game Over? Is there a way to reset game after Game Over?
Maybe bugs:
1) I just try to add some scripts to "On Enter" level function:
Test 1! {transform-avatar mer} Test 2!
All text working good! But line "{transform-avatar mer}" isn't working at all!
But it's working with object scripts.
