Is it possible to make the same game twice in the first day but in different game engine? Is it possible at all to upload more than one game?
I have watched the release video for this jam, and there was nothing against this mentioned. I believe you can, but for the sake of attention, you might want to work on one game. If you make one game that is more complete, other devs will be more willing to pick it up and build it into something greater. But if you have the time, I suppose you could do that.
How it works is: first day you START a game
Other days you continue work on games you DIDN'T participate in yet starting from previous day project files. So you could take another game written in another engine and try moving it into a similar direction of your first one I guess? You cannot submit 2 NEW games either way
