Galaxian in C

Galaxian is an academic project developed for Digital Games from PUCPR. Any comment or criticism are welcome. First game in C using console, so its not a big deal, but I hope you enjoy! Based on Galaxin from Atari 2600, you have 2 minute2 to kill all enemies or YOU WILL DIE!Controls: Press Enter to start, Arrow keys to move and Spacebar to shoot.
