Beautiful graphics!
If anything, I would suggest trying to be consistent with the pixel sizes; the tree where enemies spawn from seems to be scaled differently from the sprites used for the fox and the companion, which makes it look a little out of place.
I would also suggest adding an option to adjust the bloom in the game, as some players prefer not having it.
The controls felt fine too, I just wish I could reload the turret without having to shoot all of the ammo first.
Other than that, I enjoyed the narration. It really gave character to the game! Subtitles would help a lot with accessibility, especially for the tutorial parts, where players may miss the dialog.
Nice job!
