It'd be a nice addition.

All the other Triangle Service games work on Windows 7 so I was a bit surprised that this one does not. And I read the requirements just now, and I see now that it requires Windows 10 but here is hoping :D

The game frequently reverts to windowed when fullscreen is selected, freezing control and requiring the player to click the mouse to resume playing.

I've beaten both Tank A, 8bit and building dodge while playing on the age test (not challenge) and it didn't unlock anything to me. It's probably safe to assume that it's the same with Tank B and bullet dodge. (funnily enough, the young achievement was fine) Just thought I'd report that....
