I see below from other commenters that the inertia on the player character is divisive. I also didn't really care for it.
Very evocative of the game boy Legend of Zeldas, super nostalgic to play. Lots of "gameboy soul" here for sure, other than the font used for text. Changing that to something more pixel gameboy-ish would help a lot to make it more cohesive, as it is it kind of sticks out because the rest of it does such a good job being authentic.
I think I found a bug. I went from the "secret station" to the bottom center planet and shortly after landing had this text at the bottom of the screen and couldn't get rid of it.
