"A Slice of Heaven" is a space-themed rail shooter in the style of Starfox 64. The player controls Frey, the commander of an elite squad of fighter pilots, as she flies across a plethora of beautiful, exotic landscapes, routing the enemy forces wreaking havoc. On your journey you'll be accompanied by your loyal crew. As you complete missions and overcome challenges, you'll get to upgrade your allies to make them better at taking out enemies, defending objectives, spawning items, finding weak points, or even finding new hidden paths that lead to entirely different missions! And whether you succeed or fail, these upgrades will still be there the next time you play, increasing the effectiveness of your squad until you can finally uncover the mystery behind the evil empire, and Frey herself.
