If you have ever played Mario Paint for the SNES, then you have probably played the Gnat Attack game (also known as Coffee Break). brunette_redhead’s game is a spinoff of this, created for the Wii.

There are two main game modes, the “Classic” mode, which is level based much like the original. There is also a “Swarm” mode which features endless enemies.

Changes:

Fixed bug that could lead to crashes during close
Added many new graphical effects
Added high score for Classic mode
Added new skins for bugs, you can choose this at the main menu
Much much more…
