It's mega short and really good practice for other games with high emphasis on directional combat priority like Metal Slug or Contra. Fall of the Foot Clan is a quick 2D side-scroller where nearly all enemies die in one hit, boss patterns are extremely basic, and graphics that do a lot with VERY little. It's not going to blow your mind, but if you like the genre it'll make you smile! If you really loved it? Check out the GB Castlevania titles next for a similar structure with slightly elevated difficulty.
