Mars Base Sim
You are stranded on Mars and all forms of power generation have been destroyed by a devastating dust storm... except for one: a manual charge button. You'll need to click to generate charge for the entire base, luckily you still have access to a 3D Printer to build components! Restore the base to it's former glory and find a way to get back to Earth.
Note: game state is saved if you close the page, but components are not saved. Instead their cost is refunded, so when you load up again you'll need to repurchase them.
