HHHAHAAHHAHAH but also kind of bad
you get 6 stars for the funny humour (of seeing a man attempting to jump over a car and failing so epically at it.) I loved the artwork.... detested the music, but everyones different, i guess.
Unfortunately the game concept is overall weak and its virtually unplayable (I don't know if this is your fault and the programmer, but the man's jumping would often lag after pressing the spacebar). I don't have anything against hard-to-the-point of imposible games, but for me, it would depend on how long the guy would 'choose' to wait to jump after I pressed the spacebar. Its kindof like playing rockband when the audio is slighty ahead of the notes.
Now I haven't ever designed a game, so i understand that I can't possibly preach to you about gamemaking, but what I and many non-designers on ng can do is compare the qualities of your work to others, which you should find very helpful and be happy for (even if people just put in "lame" cause at least they're being honest).
hope to see somethingplayable later,
And PS, if u make a sequel, include many more death scenes and different car dynamics/jumping moves, cause that would be sick!
