Grinning Cobossus is a shmup that only consists of one epic boss fight, but it features 3 difficulty modes, survival mode, 12 achievements to earn and a lot of fun.

v 1.09 Added a 3-seconds delay after unpausing the game

v 1.08 Various bugfixes, mouse is now centered on the ship, also fixed a bug that occured in survival mode

v 1.05 Fixed health regeneration issue. Also, scores in survival mode are updated each time you hit the boss, the score won't be ignored when quitting via the exit to menu button.

v 1.04 You can now suicide by pressing the "9" key two times in case you wanna quit survival mode. (It won't save the score unless you die)


Mouse - move (mouse controls)
Left mouse button - Shoot (mouse controls)
WASD / arrows - move (keyboard controls)
X / L - shoot (keyboard controls)
F - toogle autofire
K - toggle keyboard controls
Space / P - Pause
M - mute all sounds

The game's a pun on the legendary flash game "You have to burn the rope". The Grinning Colossus was used with mazapan's permission.

Feel free to leave feedback, especially since it's my first flash game. I'm open for suggestions and tips, but also bug reports.

Hold on a sec...

i thought you couldnt kill the cobossus using normal means, like shooting, i thought you could only kill him by burning the rope! i should know, i tried throwing axes at him for like 10 min...
Anyways, a nice little vertical shooter. kept me rather entertained.
