A couple years back I bought this game along with quite a collection of others and an old Master System for a trip down memory lane.
Honestly, this is not a hard game at all. In fact I got bored after a couple of stages because its just the same thing over and over again.
If you want to talk about hard Master System games, play Astro Warrior, if you die so much as once anywhere after the first half of the first level you're absolutely screwed.
