Control a Martian Exploration Rover to discover traces of water, maybe even life on Mars!
Arrows/WASD move the Rover. Shadows deplete solar power faster, recharge in sunlight.
Watch out for the sandstorm as dust slowly covers the Rover's image sensors!
'A monkey named Gavin has to ride a horse or a unicorn into a castle. Gavin lives on Mars and wears a crown. He is playing games and stuff in the castle. The name of the game is "Gavin on Mars." (Courtesy Eric, age 4)'
A Kickstarter request. I tried to keep the difficulty down in the hope that Eric might play it. There's a wee dedication to him if you press the 'E' key on the last screen.
Gavin on Mars: Eric Expansion Pack
Eric, and SpindleyQ, have since expanded on the game, which you can get here: http://www.glorioustrainwrecks.com/node/2833
