Hammer Man X, A Bootleg Oddity

Whilst taking my regular stroll through Ebay, I came across this rather odd Mega Man X bootleg, one that I've not only never seen before, but also just so strange that I felt compelled to post it here.

Behold, "Rockworld." Rockman Mega World, it is not, but something entirely different. The seller's description of the game sums it up nicely:

"Classic, addictive gameplay - Mega has to take his hammer, and run around creating holes in which to trap various nasties (robots, insects, mammals and monsters) before knocking them through the floor to their doom!

Collect various powerups and bonuses to boost your score and gain extra skills. You can even plug in a second pad and play with a friend! Genuinely good fun, and really hard to get hold of!"

Quite the kooky situation X has gotten himself into. Maverick Hunting alone must not be putting enough food on the table, I assume.

Now, I can't exactly place my finger on it, but the game looks like its based off of something genuine. At a glance, I thought it was either Wrecking Crew or Mario & Wario but that isn't so. Any ideas? Nevertheless, I'd kill to see some gameplay of this!
