Cool game, I like the concept. We were also considering making a rocket launch :D
The graphics look good and clean. Minigames were fun and easy to understand. I don't remember hearing any music, though? I didn't experience any bugs, and had a problem free launch :)
I think some variations to the puzzles could be introduced to increase the difficulty. For example:
- More buttons/steps in the pattern repeting game
- Change the symbols in the matching game
- Reverse order in the number sorting game
