Run time : 05 :46 Nice metal ending. I think I chose the right path by chance at the end on my second try, didn't get the puzzle with the password, but it's fine.
On one hand the vibe I got from the game was not specially typical NES, I think mostly due to the resolutions of the sprites, but on another hand and even more important it was pretty fun to play, I enjoyed the controls based on accelerating and decelerating, the actually different levels between the one where you're going fast and the boss fight and the fine difficulty.
