I managed to complete all levels with several retries, I like it regardless, fun and a great concept! Could use an arrow indicator when the astronout is off the screen though because most of the times I'm hesitant to launch the astronout instead for I'm not sure where I should be catching, that I chose green gate holding a lot when given the choice.
Also the music and sound effects are great, especially on restarts, it made me laugh almost everytime. :)
