It's a nice premise and the art is very cute, I really liked it, even though it could have been a bit more cohesive (ie: using line art on the assets for the cafe area, but not for the lake area).
Unfortunately the controls were quite confusing, as other people have mentioned, and once I visited an area on the map, I couldn't figure out how to leave it again and had to refresh the game and restart. I don't know if it's a bug, but I didn't seem to be able to fly in the lake and cafe areas? I assumed I would have to fly upwards to get back to the map, but I wasn't able to do that, so ended up wandering off the edge of the screen and not being able to come back.
As someone else has mentioned, for me the game only showed up in the top left hand corner of the screen, and like them, I'm also a Mac user. I'm not sure what causes it but it's an issue I've encountered with other games made in Godot.
Lastly, I think putting more work into the sfx and music would also go a long way to improving the game feel and atmosphere.
Good job to your team on making your first game!
