Killer Rabbit Online is a co-operative, competitive, 2d platform/shooter/survival game. There's a giant killer rabbit on the loose, and all the players set out to kill it. Due to its great strength and agility, an individual will have trouble killing it alone, so the players are expected to team up to defeat it - however, everyone wants to be the hero known for slaying the killer rabbit, and so all players compete with each other for medals.
Dodgy mock screenshot follows, final game should hopefully look far better
The orange health bar on the red player shows that he's been carrot juiced by another sneaky player, making him a more attractive target for the killer rabbit.
I haven't coded in years, and have never done any netcode before in my life, so the 'online' part is maybe a bit unlikely, but hopefully I'll at least have something playable by the deadline.
Edit: screenshot removed, no longer on the server.
