What happened to Survey Team 4?

It's been a year since Survey Team 4 landed on Osiris 4. They reported a peaceful planet with the highest density of life signs ever detected. And then .... nothing. No response to communications, no emergency beacons, nothing at all. What happened to them?

What happened to Survey Team 4? is the third chapter in my One day at a time series. The series was begun as a means for me to practice coming up with simple games. I set myself a few rules to try and ensure they games stay simple:

• I get 20 hrs to develop and upload each game.
• No individual game can be released until the collection is complete.
• Once all games are complete I get 4 additional hours per game to polish them.
• All games are done solo but I can use third party assets.

With the rules in place the question was then what would I use as prompts? I decided on working my way through all of the Global Game Jam themes in order. What happened to Survey Team 4? is based on the 2011 theme of "extinction".
