This is very neat! I enjoyed exploring.
The planet's design, the lighting, font and background are all excellent, everything is smooth and beautiful.
The soundtrack is absolutely great, it didn't get annoying at all and was overall awesome
The gameplay is cool but towards half of it, it seemed too slow for me, maybe the patience factor was intentional or maybe you could speed up the planet as you explore more (since you are becoming a better explorer you are also faster at it idk)
Overall very good :) Well done.
