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.

An extremely fun 143 seconds, full of laughs and epicness. A little short, but awesome nonetheless.

Yeah, that mode was designed to be a challenge for the shmup pr0s - kind of failed in that matter, though, most of them think it's a piece of cake.

Incredibly fun game. I came here from the Flixel website. It's amazing what you can do with that software.
I wish I could do games like this, but my programming skills suck.
The game is incredibly fun, although it lags like crazy. Excellent job you did.

Gama11 responds:

Flixel is not really a "software", it's a framework for coding in AS3. But either way, glad you liked it. :)

Its a good game but a little hard for when i just want a quick game, could probably get used to it after a while though. I definitely like the idea :)
