It seems all too easy to be forced to a loss by the RNG. Other than that, there isn't really much in terms of skill to the game, as the screen isn't large enough for you to really be able to see something and plan in advance whether you want to waste energy moving towards it or not.

Hi, there's really serious showstopper bug that when walking on a planet if player go outside screen then game gets stuck.
Interesting mini-game, however it's depends more on luck rather than mind. I think you may be telling a story about return to earth but maybe some information about who the character is and how to find earth would makes it better mood. Just personal thoughts. I like the art very much and also the feel of mini-screen.

The ship movement felt a little bit too tanky (It would be nice to have a little more inertia since you are in space. The lack of sound really hitted your game, adding an ambient music and some sound fx would definitely improve it.
