Superb game! The last couple of games had me thinking a lot and solving tricky puzzles so thank you for not making me do that :P
The game feel was awesome, the audio was great (so cool that you have live music!) and the visual aesthetic really worked for me. I loved how the moon was spherical and I could go around it.
The master AI took me maybe 4 tries to defeat and I was very satisfied at the end. But then I saw there are 2 endings and twice as many power ups as I found, wow that's so cool! I plan to go back and accomplish more. Really good stuff.
