Level Up!
========
10/10, a good reason to play one level.
Summary:A guy crashes in your garden, and remembers only about magical floating gems, collect them, do normal things, level up your stats, and defeat the ultimate evil that lies within your dreams.
Upgrade Complete
================
8/10
Summary:You are a ship. No, more like a polyhedron of some sort, and you must become the greatest ship known to your kind, so you defeat these other Polyhedrons for points which you spend to upgrade your ship, the game itself, The logo,and your experience.
Achievement Unlocked
===================
7/10
Summary: Peh, well, after a while, it gets boring, some of the Achievements are unique, but it all gets very monotonous, or something, after a while. There is no real Story anyways.
