A decent first attempt...
but needs a lot of work. First off your "Instructions" & "Credits" buttons don't work.
And the misspellings of 'olmost' and 'relplay' make it seem n00bish. You definitely need more than one level in your flash, for something simple like this. Make it go a little faster, your translucent slug thing goes way too slow. Maybe add coins or gems or something collectible. It really needs something more gameplay wise. Practice a bit and your next submission should be a lot better.
