Thank you for the feedback Loot Saga! I'm really glad that you wanted to play the demo of Underground!
I would like to refer to the issues and advices you have presented:
1.When you hit the escape during or at the end of the tutorial, the pause panel should show up and there you've got 'menu' button which redirects you to the tutorial selection scene.
2.That's my mistake. The arrow should disapear, so I'll fix it in the next patch.
3.To unlock the next step in the general training, you have to move your character, by pressing 'W A S D'.
4.That sounds interesting, but I'd have to rewrite most of the machine's code.
5. The new method of calculating points is really cool and I'd like to implement it.
Thank you once more for the support! :)
