Made this for a TIGSource competition with the theme "Versus".
Exuberant Struggle (windows)
Currently it only supports exactly two players, both on the same keyboard (WASD vs. arrows). I had a vague intention to add AI and networking sometime, but they both seem unnecessary now.
It's a sort of action/strategy game. Resources pop up in the middle of the screen, players control ships moving along the edges, line up with resources to pull them towards you and collect them. Then you can spend resources to make units and fire weapons (which are chosen from random options given you).
edit: updated (21/03/2011), new win condition and stuff, see tigsource thread if you want the details. updated (26/03/2011), minor balance tweaks, hopefully not going to tweak it any furuther.
