Very buggy
Good concept, decent execution, bad bug checking. List of annoying bugs: full auto upgrade being applied but not taking effect, guy not shooting when I click at a long distance, shop menu disappearing down to 3 items, getting sucked into the crack between 2 cars in the opening cinematic for level 5's boss, and most annoyingly, hitting level 5's boss point blank (yes, the pilot!) but not doing any damage. Its fun, but incredibly frustrating when my guy goes and kills himself uncontrollably for 1 life and durps in circles not attacking for the other 2.
