Thanks so much for playtesting for Cat Powered UFO!
To other developers reading this.
If you are serious about making your game as good as possible I highly recommend gamercomposer.
He makes videos of himself playing your game and speaks his moment-to-moment thoughts for you.
This is really useful, it's likely you'll have many oversights in your design that you are completely blind to.
Seeing someone else play your game in real time helps identify these blind spots.
