Oh, I wanted to like this, but my brain was like, "What are these controls?" I couldn't get the hang of them. I think this could be fun if you made the controls a bit more user-friendly. And when I did finally get my ship to the circle (Stage 1 LOL), I was very sad when I realized I also had to STOP my ship and keep it in that circle for a # of seconds. So... I got excited... and then immediately upset :-D
This game could be fun/challenging for certain people, but I think the controls will be very unpopular amongst most players, and remember... you want your game playable by a variety of people.
Good luck with your game! I'll still follow to see what kind of updates you do in the future :-)
