For the game - I would be delighted to test it, but most likely this weekend or so. (Plus, Java sadly isn't the most user-friendly interface for browser-based things.)

For getting feedback from quantum information researchers, I recommend posting to https://www.facebook.com/groups/qinfo.scientists.unite/.

I see that you have similar taste/inspirations to mine (I am also a big fan of Test Tube Games (Velocity Raptor & Agent Higgs)). See also: https://hackpad.com/J0X4MSberlM?r=0 for more picks (and feel invited to add more).

For quantum games - in a week or so I plan to release my own - https://github.com/stared/quantum-game
