absolutely peak, the best FREE game of this genre I could find. I played this game back in 2019-2020,the only problems I had were the bugs with the wormholes whenever a satellite would enter it would forever stay anchored at the other wormhole. another thing is the list of each planets, rocks or any other debri in space, whenever you place a lot of stuff and try to find a specific thing it would nearly impossible to find bacause there's no sorting in the menu. but the game is fun and relaxing.

AMAZING GAME!!! COULD YOU PLEASE ALLOW planets with civilizations and satellites to send probes to other planets in system? Maybe you could add in technology trees, and give us the option for something like developing an AI-driven space program? It would be astonishing to launch a mission between worlds, but between systems?!?! MIND BLOWING!!!! PLEASE KEEP GOING WITH THIS GAME!!!!!!

Very fun game, good graphics, I like 'unlocking' new planet types, and I like to have life appear on planets. The -1 star is because its very difficult to get planets in stable orbit, especially in the right orbit distance for life. Really fun, I definitely recommend it. (Also, if you could add more planet/star types, and have more things happen when life evolves on a planet, that'd be fantastic 😊.)
