I've gotten to and past level 20, fully upgraded my ship, somehow bought the mystery upgrade, got all three medium achievements. Maybe I should buy the save system or achievements.
I found a bug. If you immediately hit go after a battle, before it slides back to its original position, then you can hit go next. If you don't, you may end up like I am, running from an enemy with neither of us getting anywhere.
Good idea, but the game keeps on freezing my mouse. This means I have to leave the bubble, get my mouse working again, and then reenter the bubble I was in.
