Objective:
Blast off and strike the evil green legion of mutating ships from outer-space!

Instructions:

Move your main ship around with the arrow keys.
Shoot with <z>.
Holding <z> makes your ship go slower.
Once you level up and gain extra ships you can do a power attack with <x>.
Power attacks deal a lot of damage and clears all enemy bullets but it takes a while for the extra ship to cool-down and be useful again.
Extra ships follow you around shooting forward.
If your main ship gets destroyed, the next extra ship becomes your new main ship in its place.
In short the extra ships are: lives, bombs and helpers in one.

Features:

Lots. Of. Bullets!
Randomized procedurally generated enemies, mini-bosses and end-level bosses. Every play-through is different.
1 bullet hits the enemy = 1 experience point. Each experience level reached makes your ship more powerful by giving you one of these: extra-ships, increased bullet shooting rate or increased power attack and lower cool-downs.
No penalty in death. You keep your experience points and experience level, you just restart the current level.
10 different levels and infinite new game pluses with increased difficulty.

Influences:

Shooters: Zanac, R-Type, Gradius, Cave Shmups, Recca, Raiden, 1942.

This has been my most ambitious Pico-8 game yet and I would greatly appreciate any feedback you might have... also, I'm interested to see how far people get on the game. Enjoy!
Special thanks to everyone on the pico-8 community for the help, encouragement and awesome little code snippets! I <3 Pico-8!
