Thanks for the kind words Alex! :) Glad you liked it!
Hmm, maybe you were almost out of gas (upper right corner). The game only resets when you run out of gas, but the strength of your shot is limited by how much gas you have left. So you can get in these funny situations where you have barely any gas and game over is guaranteed considering your distance to the black hole, but you need to make the last "pathetic shot" to trigger the game reset anyway. That is definitely a user-experience thing which could be improved upon, hahah.
