Thanks again for the feedback. I'll have to think about what you said.
As for my future plans, I think Tutor 2 could go on a lot longer than it is now (it won't end in the next update). But I'm thinking about maybe pause it for a bit, I hzave an idea for another, more fantasy story.
To a sandbox style gameplay I have to admit that I don't know how to write the script for something like this and I don't have the time to learn it at the moment.
