I like the opening with the voice acting, that's a nice touch. And the spaceship visuals are nice. Seeing the starry cosmos with the occasional asteroid whizzing by was pretty cool.
I didn't like that there were no clues or signs to look for when piloting the ship. I just got lucky and found earth by wandering. It's especially tricky since the planets look black from a distance. They would have some color in real life, even Mars and Venus have a visible tint when viewed in the night sky from Earth. Plus, Earth looks different than most players would expect. This is a nice thematic detail, but maybe a hint that "it's the big brown one" would be a funny way to tell the players what to look for.
I'd like to know how there are new planets so close to Earth as well.
I gave up when I couldn't find the digital chip. The environment gave me no clues and looked mostly the same all around, and the compass didn't help at all, I tried following the skinny end and the wide end, both directions just pointed to invisible walls. You can't even go back to your ship to scan for signs of the digital chip or anything, it just says "spaceship is locked".
Finally, I don't like that there's no speed boost when you're on foot. If you put me in a big open landscape with nothing to look at or interact with, I'm going to want to move as fast as possible to the nearest point of interest or I'll get bored.
Thank you for sharing your game and good luck in future projects!
