I'm not sure if I'm the only one who remembers that old Windows 2000 game "Jumping Jack" with this little guy in the space ship? You basically do exactly the same you do here, but it's way easier at the beginning, thus not frustrating for the player already within the first level. Well I guess everybody who knows the game I'm talking about would agree with me that it's more entertaining. I don't know if you (author) know that game but it looks like you basically took the idea and remade it in pixel art, raised the difficulty and limited it to seven levels.
Your version is definitely too frustrating for me to be fun, sorry. :/
But I liked the starting joke, so 2 stars.
