Im making a level platformer, and my original idea was somewhat ambitious for only a week, but after constant work and shortcuts, I think I can get 40-50% or so of the game finished by the deadline.   What about yall 

80 or 90%, because I have a simple game idea, but I don't think I'll have enough time to add more levels.

95% ish cuz i didnt polish my main menu/end scenes

Prob 40-50% like you, because I had to switch game idea halfway in the jam because it was too hard, so now I'm working hard af on the game, but I know it's not going to be done by the deadline, I will continue on the game after the deadline but still it's not going to be done because of that.

prob 10 because I have lots of ideas so I'm going to work on it after the jam(but I'll give the jam it's own page)
