Congratulations on the C++ move, and hope it pays off in the long run. The game runs out of the box on my Manjaro desktop. As for the game, all I can say is that what's currently there seems to match the experience in the LibGDX version. I assume the reason why rockets don't damage the player is that combat isn't ported yet?

It already feels like C++ has paid off, just the amount of power you get access to is incredibly liberating. That'd be correct, there's no damage calculated for any projectiles yet, you can only get hurt by fall damage in this demo. As long as I don't waste too much time playing 4X games before next demo day I'll finally be back to adding new features instead of reimplementing old ones.
