Wow, we had the same idea for the game mechanic! We even used the same flying sound :D I liked how you animated the background. More information on the planets would be nice, so that the player can calculate risks and not just navigate by random.

The visuals are really awesome and pollished! The gameplay is simple but enjoyable, of course the game mechanic seems to be always the same action (clicking on the same looking circles), but it is still funny if you get damaged all the time xD. SFX, UI and animations are also clean. That game could be very good for developing it further, keep it up!

Really cool concept - very much an exploration game. Would have loved to have seen more depth to the mechanics.

This is a cool little game. Here are my thoughts:

Pros: the visual feedback is actually pretty satisfying; when you move to the next circle, the ship does a little squash and stretch thingy which was a nice touch. I thought it fit the jam them well, because you're literally exploring trying to find planet X. It's also the perfect length for this kind of thing; you can play this thing in a minute if you want.

Cons: Because the mechanics are simple, there's not much for strategy here; you're clicking on a spot and waiting to see what happens, with no say as to the outcome, which makes it get boring pretty quickly. It's the equivalent of rolling a dice, looking for certain number, and if you roll that number, you win. That's not gonna be very fun for more than 30 seconds. Also, the text popups have a lot of text. The attempt here is immersion into the world, but because it has no tactical impact on game play, I really didn't care about it. If I lose fuel, or gain fuel, I'm just going to choose the next random circle to go to and hope it's Planet X. 

Great job though! Good presentation overall. Keep up the great work, and keep on coding.
