Game: Tinmen Turmoil
In the future heartless robots destroy mankind. Realizing the folly of their ways these "Tinmen" desperately search for love by collecting hearts, thinking that this will fill their empty souls. It's a 4 player arena battle; the player to the collect the most hearts wins! Two players on keyboard and two with controllers seems to work best. You can play it in a browser, but it seems to run slower there. Also there's no AI (ran out of time) so, you have to have two or more players. Have Fun! (BTW - It also meets the "Approved for All Audiences" diversifier below however I could only select 4).
