I’m in!
Hey!
After having a small-one-jam break, I’m in for the LD #30 ! Yahoo!
I’m using, as usual, Love2D, GIMP, sfxr, some neat libraries for Love2D (ANaL for animation, Love-debug and also a network library).
Also, potentially I can touch GP5, TuxGuitar, MilkyTracker and Inkscape.
Today I started pretty late and after 2-3 hours of work I have 200 lines of code and a working “Angry bird” clone 
The game is about beetles! The idea is that we classically throw animals into buildings but here’s the twist: something went wrong and our game universe got expanded: somehow we met another thrower! And moreover: he’s trying to destroy our home! So we need to hurry and destroy him before he destroys us!
The mechanics is a mix of “Angry birds” and “Scorched”. We’ll see how will it blend 

Beetles attacking :)
