This is my first jam, I´ll be entering alone though it´s possible that a friend may end up helping in some way. I´ve never done anything remotely similar to making a game in a couple of days, so any tips are more than welcome :)
Welcome! IMHO after we disclose the jam theme you should try and find a nice little idea. Something simple that you know you can develop in a small amount of time! Then you can spend the rest of the weekend to polish and upgrade it.
Cool video! Getting my son into game development and asked him to take on the role of game designer for this game jam. This video will help him (and me!) a lot. Thanks!
