Good

Best game ever, but where is sfs2

Amazing Game

Brilliant game, love it on my phone, can spend hours designing different rockets and I'm only playing with whats free.
One request, I also have this app on my macbook and it's not nearly as good, but still enjoyable. My request is that you add RCS thusters and Docking Ports to the unpaid version just to give access to a few more projects you can build.

iPhone locking up

Update: I suspected the then most recent iOS update, but did the next update and it still freezes my phone. I have to shut it down & that doesn’t happen normally. At times I fear I’ll active 911 without knowing.
(Old review)-Recently the app freezes my phone. Cannot escape the app and takes repeated tries to shut off my phone. Have enjoyed this app for years and the graphics continually improve. If not for locking up it would be 5 Stars.

Wow good look

This is SFS like on SFS multiplayer

…. Dude where do i start??

A excelente game building rockets and more is fun
Built a great ion rocket and more just some more skins would be nice but other than that it’s a great game the update adding full soler system and water is fun to do recreating Artemis missions and more it’s such a fantastic game defiantly recommend to all people that love space games. This game brought so much fun and will never get boring let’s wait for sfs 2 that will be a banger as well. Just a great game all and around. I love to build the rocket definitely recommended to do falcon 9 missions and starship ones with reusable rocket boosters and more just a alsome game and will always be rememberable
