Hello!
I'm excited to announce that 39 Days to Mars now has a 🚀Free Demo 👨🚀 on Steam, which you can download and play right now.
It'll take you (in singleplayer or co-operatively with your friend) through the start of 39 Days to Mars, solving a few puzzles with Albert and Baxter, and embarking on their ill-advised voyage to have a cup of afternoon tea on Mars.
I hope that you enjoy playing it,
Philip
