Hey there! Sorry about any spam comments, I've had issues for a while... It sounds like the save selection is picking up a fake save file without there being a save. Try to go through the new game section again, it should work. I'll work on a patch for that crash in the meantime. Thank you for reporting!

Edit 7/5/22 - Getting an update out to fix this issue, sorry about that!

How opent gamemode selector menu ?

Hi! The gamemode selection menu shows up when you start a new save game.

Not working its bug? 

Which version are you playing? (Bottom left in main menu) O

What happens when you select new game?

*Edit: I found out what's going on, I will be pushing an update out today to fix this.

**Edit 2: There is an update out to address this, thank you very much for reporting!

Looks like this game is broken, after receiving the FTL drive and "recalibrating", nothing happens (as in no new main quests appear)

The quest menu tells me to upgrade my ship... but nothing happens if I upgrade my ship either.

Do you have all of the engine & gun upgrades?

Yes, upgraded to nuclear engine (before upgrading to FTL drive), and bought all gun upgrades (basic gun, advanced gun, railgun and laser gun).

Hmm, that's strange. I'll test it out and see what's up.


Sorry I never got back to you on this! A while ago I removed the "Stories" App from the tablet, which was the source of new quests besides RNG quests. This is not broken, the game has just changed direction, after you recalibrate it changes RNG quests over to the new quest system which works much better and has a better variety of RNG quests. I wanted to focus more on exploration and less on Quests as I'm not a great story teller, hope this clears things up! :)

Selecting the "Bugs/Suggestions/Inquiries?" option in the options menu does nothing, and I have a crash to report. What do I do?

Hello! My apologies that option is supposed to display more info on how to report. You can reply here with it,  and I'll see what I can do to get it fixed asap.

10/10/21 Update: I fixed the options menu bug, it'll be in an update later today :)
