This game really feels like an adventure while being mindful of the GB's capabilities. Such diverse environments that don't ever use tile transparency or, of course, more than 4 colours. This palette is performing miracles, speaking of. I can tell the devs really love the GB.
The one thing I'd have to say something about is the music. It's not that it's bad; far from it, it's quite good. It's just that each track could be longer, could have variations according to biome, etc. given that you're going to be listening to them for quite a while.
Also, the axolotl pirate is incredibly cute!
Great game!
