This looks ace - thanks for sharing! How did you manage to get your game playtested?
I posted the game here and there - on Board Game Design Forum, and The Game Lab at University of Shizuoka send me a mail on BGDF, ask me about my game and pnp files.
If you follow the link, you may know their work to research games and help designers to develop their work. So I am lucky that they are interested and playtest my game!
These are videos of University of Shizuoka playtest my game:
Part 1 - Learning the game
Part 2 - Playtest the game
I don't know if they'd accept any request but you may want to contact to them.
If not, you may post your game here on BGG, and describe your game. Some guys on here very happy to playtest game others as long as they are interested. (me too )
