- Theme: hm, space? limited?
- Audio: Nice, but give a feeling of mystery IMO.
- Visuals: Its simple.
- Gameplay: I can't tell much. There isn't a winning/losing condition.
Congratulations on your first game.
I think you should watch a few gamedev videos. Play alot of games and try paying attention to the details. When you play with the objective of identifying development features, you learn alot instead of playing to enjoy a game. Learn about GDD, SOLID (the 5 design principles), specially because gamedev involves programming (even if you use visual scripting).
Cheers.
