Not worth any quantity of money. It has annoyingly slippery control, which makes your hero feel like he's walking on Teflon.
The retro look is okay, but usually you need really nice gameplay to go along with it.
More work needed on graphics - aka more background objects. Time and effort gets a higher rating and a better game. Still, this game is playable, with decent hit detection.
This game is an actual game, that took some work to make. The author might actually make a good game if he worked on the graphics and gameplay. It isn't anywhere near good though.
