Game has locked up on me ... no support – Space Inversion 2 HD Review

This game is frustrating. The speed is set faster than the original Space Invaders and the "fire" button lags at critical moments, keeping scores low. Now the game has locked up on me after purchasing it, and I can't find any support contact to get the program started again.
