Small project I done to train and learn more about unity and the creation of sprites (using Piskel) - it is a simple STG (shoot them up, games like Space Invaders), it features three different weapons for the player, which one with his own system, life system (with both lives and hit points) and a increasing number of enemies. Soon I will upload the final version, once I figure where.
Space - Laser
Z - Missile, limited by number.
X - Beam attack, which the player has to wait to recharge before firing again.
WASD - Moving around.
