Gave it an other try haha.
Really great game, still there is some bug when the character freeze inside a "tunnel", I really think a R button to reset and without a 3sec start would be less frustrating.
There is still room for improvement for theses records cause I did little mistakes and didn't optimize for the third.
Btw I don't know if it's wanted, so I didn't use it for those times, but you can pause bug probably (which stop timer but do not stop canon from firing).
