Is there any specific kind of game we need to make?( singleplayer, multiplayer?)

Whatever you want I think

Its only one week so maybe to a singleplayer, but if you have time maybe add something like coop two people playing on the same screen.

it can be anything you can make in enough time, though servers are expensive so id go with singleplayer. especially since not a lot of people are gonna be online in a game jam project
