This is simple, but funny space-shooter that will be good basis for your own cool games.
Player flies forward and needs to survive among Asteroids.
Complexity will be increased gradually – new enemies appear and Asteroids become stronger and bigger. Player receives points for enemy destroying and can earn up to 3 stars reward per level. Weapon can be upgraded.
Casual and comfortable controls (just mouse or touch) to attract even non-gamers.
