Here's my feedback:
- I liked that the baloon doesn't move lineary which adds depth to it
- I Like that the map loops
- Game gets repetetive too quickly sadly
- I finished the game and went through the black hole and make kid had balloon back
- I don't think starting from stratoshpere the wind sound should continue
- The wind sound is a little annoying
- I liked the stratosphere background effects
- Not related to the theme really
Good job on the game.
