Overall, I thought this was a fun game with a cool idea behind it and also fit with the theme nicely. I liked the mix of combat, exploration, collection and trading which made the gameplay quite interesting. Also, the art is fantastic (especially with the planets).
The one thing I'll point out is some portions of the text blending in with the colour of the planet depending on where you approach it from which made it a little bit difficult to read.
Other than that, great game!
