Late but I’m in :)
My weapons :
– Language : ActionScript 3
– Library : FlashPunk
– Graphic : GIMP, MS Paint and Pyxel Edit
– Audio : Bosca Ceoil && as3sfxr
– Base Code : here
– Other : GoTile if needed
41hours left, no idea on what I’m going to do, probably something in the space, like most of the people apparently :/
Good luck all 
Edit : Well, finally I will not participate, the theme doesn’t inspire me much. Can’t wait to see all the games that will be made
