Yrgo - Game Creator is hosting its annual Zero Hour Game Jam. We will once again 
start in the middle of the night at 2 AM and work for one hour and then daylight saving 
time will set the time back to 2 AM thus making the event zero hours long. 

The theme will be announced on our itch.io game jam page about 5 minutes before the
jam starts (just refresh this page). Five minutes for design and one hour of build time.
You are allowed to use existing assets (images, models, sound, and so on).  You are not
allowed to use ready-game templates. You are allowed to create a blank project and
pre-load any program you might need (unity, photoshop, and so on). 

Once the time is up you will have 20 minutes to submit your game (if the server time
differs we will adjust the time for submission).  You are allowed to add screenshots and
make a trailer after the time has run out. You are also allowed to fix up to two game-
breaking bugs after the timer runs out.

This event can be done online from anywhere in the world. Even if you don't have
daylights saving time.

This is a very stressful event, so no competition or ranking, this is just for fun.

 Previous Zero-Hour Jams:

Please note that the server might change time before the jam, so start time might be adjusted.

We are not the only one making zero-hour games, you can also submit your game at
our friend's site over at http://0hgame.eu/ (if you like).

Good luck!
