can you give a link to the amazon page where you enter to win the shirts & figures?

sure just start here https://voiceapps.com?afmc=21 

get yourself a free Voice Apps account and the game(s) / skills you create regardless of the game jam itself will get you hooked up.  

Voice apps will provide all of the tutorial videos you need to get started.  I have to tell you i found it incredibly easy and I'm not a game programmer.  I'm just a game designer with some experience with game engines like 

The definite prizes from using Voice Apps are:

Publish your first skill and earn a custom Alexa Developer T-Shirt.

• Publish a skill with support for Alexa-enabled devices with screens, like Echo Show or Spot, and attract 50 unique users for the first three months, and you can earn an Echo Spot.
• Publish a skill that supports Alexa Gadgets, and earn a 2-pack of Echo Buttons!
• Publish the three skills above plus two more by October 31 to automatically qualify for the Alexa Super Skills Collectible.
• Building these skills with Voice Apps is quick and easy! Just customize one of our sample skills and you're done!

There are also drawings for free things like $500 gift certificate at amazon and another was an Echo show, but I'm not sure when these drawings occur exactly.  I don't have any direct affiliation with Voice Apps myself.  I'm just a game designer that think this is a pretty cool service and I've already got a number of different skills. 

here is my list of skills I have made live since starting a couple weeks ago.
