4 level game, where you evade various alien spaceships and optionally shoot them with the one bullet one kill banana projectile.
From the second level background scenery passed by, with destroyed planets and giant alien battle saucers, which really should have included some in the first level. Enemy ships varied each level, and they moved much faster by the 4th level to add to the difficulty. Though I cheated and just sat at the bottom of the screen!
Nice arcade music. Basic gameplay.
Suggestions for improvement:
A mechanic to encourage the player to shoot enemies rather than just allowing them to pass by. A score counter with leaderboard, some smaller enemy types, and enemies that shoot back. Extra sound effects, ie explosions. A bit more polish on the particle explosion then release for 0.99$ on Steam (not joking) :)
