Global Game Jam 2020

1 day to go and the Global Game Jam 2020 will be in progress. This year I will participate at the Jam Site Groningen. I am lucky to be in a team before the jam starts. This will save time.

I am seriously looking forward to this experience. Because there is only to win in this. You learn or you learn 😀

A short informational thing. The Jam requires a team to create a game within 48 hours. To make things interesting for more experienced programmers/game developers, there are ‘diversifiers’ which make it a bit more difficult 😀 Here they are:

Diversifiers are a great way to add a little more fun or challenge to your jam weekend. Sometimes they can be very helpful to limit your scope or refine your ideas. They are totally optional constraints you can choose to add to your GGJ20 game alongside the main focus of the theme. It can help your game stand out from the crowd, and you can choose up to 4 when you submit!
