Unicorn Schmup

This game will be about unicorns saving the world from post-global warming ice age. You will fight using your powers and the environment against mutated/agitated creatures and evil humans who want to capture you and harness the power of your magic!

Major features and gameplay mechanics
Schmup (shooter game like Ikaruga)
Player is a unicorn
Unicorn's attacks are upgradeable and game must include at least one upgrade to the unicorn's attacks
Food appears on screen to aid the unicorn (can heal or increase attack/defense power or whatever)
