Hi!

I'm creating a game in a game engine called Twine (HTML) and I have one problem...I want to make pixel art for the game, but support to normal graphics are only in the first version of the application. And the problem is that due to the limitations of my laptop (Chrome OS) I have to use the second version...So...Can I make graphics after Game Jam or...Is it necessary to finish the whole game?

It's your game so you can do whatever you want with it after the jam, the only thing you may want to do it leave it as-is during the 2 week ratings phase, and then carry on with improvements
