Set across strange and alien landscapes, help a group of stranded astronauts find a route to safety. Travel through time, work with your past selves and solve paradoxes as you take on this uniquely challenging puzzler.

Each level represents a brief but hazardous moment in time. Levels are completed by guiding each astronaut to an exit that matches their colour, within a limited time frame. When all astronauts reach an exit the level is complete.

- Control time and change the outcome of each level
- Work with your past selves to solve puzzles
- 60 levels to complete

Here’s how it starts: Spin a few switches, and your wandering adventurers can reach their destination. Simple enough. But then add time loops, characters bumping into each other, locked areas, and the inescapable tentacles of submerged monsters. Not so easy now, right? Thankfully gorgeous art, atmospheric audio, and rewarding challenges make this time-bender wonderfully timeless.

Level 307 Flaw

Great game. I had to skip level 307 because in my version, it simply doesn't work. I resorted to looking at the solution, and it's not what happens on my iPhone 6. In the shown solution, after creating the ghost, you turn away from the transporter, and continue with the astronaut and the ghost. But in fact, on my iPhone at least, when I turn away from the transporter, the ghost disappears. Otherwise, great game, only had to cheat twice (not counting level 307).

More! More!!

UPDATE: Still hands down my favorite App Store game EVER! Enough time has passed now I can play it AGAIN!!! 😍 Maybe I will finally figure out Puzzle #410 on my own this time 🤞😬 Planning to check out Ordia by the same devs next - this game also has great reviews.

UPDATE: So it’s been a few years since I’ve played this amazing game, and it’s still just that — AMAZING!! I will never delete this app 🤗 Once again, I had to look up the solution for Puzzle #410 and it is still absolutely insanely brilliant 👏🤩

ORIGINAL: Awesome game, really unique concept. If you like challenging logic puzzles, go on and get your $2 out. I just finished the last puzzle and have already been to the devs website looking for more! RE: Puzzle #410 - wow, what a mind bender 😱 I spent 3 days on that one.
