Hey all, I’ve taken part in the 1GAM a few times and plan to do more in the future, so I’ll be posting all the ones I do here.
Most games will be open source. Warning, the early one project codes will probably be messy.
2013
January: Space Gunner
The concept was that your a ship that captures planet stars, which you turn into turrets to fight against your enemy.
Has a singleplayer and a multiplayer mode.

November: Garden Attack
Bacially a basic RTS, tutorial in the main menu explains all. Networked only sadly, may get around to adding AI later.

I didnt understand what to do in Space Gunner
There was nobody else to compete with on Garden Attack.
I’ll have to go back and add a tutorial to it, but you basally go up to the star-like objects around planets and hover over them a bit, which then gives you a turrent. These turrents can attack your enemy, and the enemy will try to do the same.
For Garden Attack, it was a bit harder to develop AI for it so I decided I’ll try working on it after I finish the actual game.
Really just have to find someone to play with.
Small update to Garden Attack, sound on headphones now goes through both ears and edited title menu a little.
I will try Space Gunner again now I know what to do.
About half through the month, if you follow me on twitter you would have already seen but here’s my progress so far on December’s 1GAM! It has a android build also for anyone with a android phone, thinking of selling it at the end of the month on Google play and maybe iOS if I can find my iPhone.
NOTE: WIP

I’m busy working on my 1GAM entry also. It’s a riff on PacMan and is coming along nicely. Good luck with yours.
Good luck to you also 
Changed the look of the background, makes it look much better.

Since it’s going on the asset store pretty soon i decided to put my december 1GAM in it’s own thread!

Updated post with last months OGAM. Sadly, don’t expect a OGAM from me for a few months as I’m working on something special
