You are the first person that said our tutorial was good! And about hiring a voice actor.. What if one of the devs (my good friend Priem), showed us he's an even better voiceactor than he is an artist!
We will keep working on this, and maybe release it in the near future, in a bigger form, or this game but more polished (buttons that light up, better player feedback, better balancing...)
So happy you enjoyed playing!
And thanks for reporting the bug, good to know ;)
