Idle game about going to space and exiting the universe.

Its not a bad idea for an idle game to be honest.

Every time you pass certain milestones you unlock new features. You also unlock a challenge mode that unlocks other features.

Pretty much the game ultimately becomes unlocking resources and features which rapidly speed up your space ship faster and faster and faster. I was able to beat and 100% the game in the span of about a week or so.
The game does factor in offline progress.

There is one achievement you might miss if you finish the game, but mentioned in the guides page and its just clicking on one hidden square....thats it. So you can 100% the game pretty easily in your playthrough.

Excellent little incremental game to pop on the second monitor while you're doing other things.
