About this game

Major new update!

SPACEPLAN is an experimental piece of interaction based partly on a total misunderstanding of Stephen Hawking’s A Brief History of Time. Use manual clicks and the passage of time to create and launch potato-based devices and probes from your nondescript satellite orbiting a mysterious planet. Unlock the mysteries of the galaxy or just kill some time in what the astrophysics community is calling the ‘best narrative sci-fi clicker game of all times’.

FEATURES

* Fifteen starchy items to unlock, create, and blast into the vacuum of space.

* Life affirming, silly story that will both captivate and help you kill time.

* Reveal the secrets of five different planets across two different realities.

* Banging soundtrack, as is customary in a narrative sci-fi clicker game.
Solve the mysteries of the universe with potato power!

decent. has a fun approach to the idle mechanics. yet, I cannot bring myself to play it. the transitions between phases, are some person's late night, shroom fueled nonsense that has little no relevance to 'story' - that you can't skip, can't close the app and reopen, you have to sit there and watch it. if your phone times out, it pauses. if you restart the game, it restarts and you have to sit through it. it seems to not end. my time is more valuable than that.

Game is amazing, but way too short. I don't regret paying for it but I feel like there should be more than a few days worth of content on a pay to play game. However, story is great, The ai companion is pretty funny, and the upgrades are actually useful no matter what they are for. Only reason I'm knocking a star is again, too short. But I hope we can see more games like this, cause this is a true clicker game in my honest opinion.

very fun, incremental game. no ads, no boosters. just good scaling. I've played idle games for decades and this one at the top so far as retention of my interest. I did notice a small bug where when you set the value to joules, upon restart it changes back to watts on the main screen but remains joules in the upgrades menu. other than that, i have noticed no game-altering bugs!
