SPACEPLAN is a space clicker game based on Stephen Hawking’s famous book A Brief History of Time. Your mission is to launch probes to the mysterious planet to generate power for your ship. Start by clicking the white button to generate initial power sources. Then, you can use the energy to build new sources and probes. Some of the probes you launch may get destroyed, so you need to research some upgrades in the Idea Listener section; you can also increase the power that is generated. Enjoy various discoveries and go with the story. Keep going until you gained the highest possible power. Have fun!
