Holy cow that was fun.  I feel like I got a lot done in the allotted 48 hours, too (so much so that I actually had to cut some stuff because the game was getting too complex :P)

My game is called Interplanetary Defense Alliance, and it’s basically about a group of planets who have to fight off a never-ending swarm of enemies by swapping out different resources between them.  I was originally going to have your ‘resources’ be soldiers of different types, all with different strengths and weaknesses towards the different enemies that showed up, but then after trying to draw some good soldiers I was reminded that my pixel art really sucks :P.  Its probably for the best; I think my other idea would’ve been too complex and wouldn’t have allowed for the polish this simpler version allowed me.

Anyways, I hope you guys also had a good Ludum Dare, and I hope you enjoy my game! You can find it right here: http://www.ludumdare.com/compo/ludum-dare-30/?action=preview&uid=39104
