"Hey! I'll just put a bunch of enemies before the castle!"
Learn everyone, learn!
Anyway, that sentence pretty much sums this hack up. Levels felt like they were rushed in design. No gimmicks, no entertaining ideas and the likes. Most of the times you just had to walk on grass filled with enemies. Not much more to say.
Same goes for aesthetics. They are okay, since the author didn't even edit the original game's palettes, but the scenario is way too empty due to no decorations at all. Makes the hack feel even more empty than how it already is.
