I played it without using the instructions provided at first, so it took two or three tries because I misunderstood the radar and I sometimes wondered if I was even doing the right thing or if I was missing something vital, but somehow I managed to get to my ship with 01% oxygen left! Only then did I check the instructions and could, now that I understood things fully, find my ship with 32% oxygen.
It's a very cute game! I like the graphics a lot, and it's neat how your speed is different depending on the size of the planet you're on. The music is calm and cozy too -- while the game would benefit from having more in regards to menuing and tutorial, I have no complaints about the gameplay itself. Except maybe that sometimes a blind jump leaves me floating through deep space for several seconds because I miss all the planets... But that one's probably on me.
So, nice work!
