Without spoilers, how far have you got?

I'd like to ask what secrets you guys have found, but they are of course spoilers.

I've managed to get to the red target system and died there... Let's just say I'll make sure my hull is at 100% before going there next time.

I reached the green ending. I hadn't realised the coloured markers were immediate endings and was actually kind of disappointed as I'd just managed to build a really good ship :p.

Ditto, I just pasted a request to have an 'this will end the game' message as I would have preferred to push on

The ending I got seemed rather well set up for just letting the player continue exploring afterwards, to be honest, so even a "Would you like to continue playing or return to the main menu?" prompt might be a potential alternative.

KINDA SPOILERS
Hmm I think it's different every time lads
Once you do that (green gate) you know where to go next time
After red gate tho you have the full story and must proceed accordingly; I didn't die because of red, just got unlucky jumps after and ran out of juice

Got to Red- now I have the narrative, sadly could not complete the final mission. Doing it will really require more than optimal play.

After a bit more time in, it seems that once you have the narrative (either from encountering green or blue) you don't have to go all the way to red, unless you need to for the Death Seed and Blackhole Warp Drive tech gift. I found my way to red a few times now (of course with blue showing up right before and doing what blue does, thanks people death) and then ran out of fuel trying to get back to get the job done. next time i get a good game going i will secure what i need and do what i need to without having to travel all the way to red... unless they gotta get done too
happy travels

I made back to earth :3.But i don't know whats up with the blue one

Finished the blue ending a few days ago, so that's all three for me. Now I just need a sequel.
