Pros:
- Amazing graphics and effects
- Nice audio
- Fits well with the theme
- Intuitive controls
Cons:
- Wasn't too sure on how to win, I ended up just going around collecting the blue collectables and flying through the black hole out of curiosity
- Add a sensitivity slider setting if you continue developing this game, my mouse was really sensitive on this game
Overall: Pretty good game considering it was made within one week! :)
