Despite giving the game a 5, I like it. It's easily the best NES beat em up I've ever played, and has a ton of charm.
Combat's really simple but feels good to do, but does wear thin near the end of it's pretty short runtime, especially with all the bosses feeling pretty samey and easy to cheese. Also I got hit as soon as I entered a screen enough times. That got annoying. I like the idea of the rpg mechanics, but the main issue is that you don't know what items will do until you buy it. So you have to waste money (or do what I did and check a guide) to figure out what's a good deal. Overall, a neat game that feels dated but not annoying.

This game is an interesting case. The gameplay is pretty fun, with a variety of obstacles that get iterated on well. The problem comes in with the game's lack of originality. The mechanics, music, story, and visuals are all fairly standard. Nothing is particularly offensive (except for some cringe dialogue and very bland UI), but nothing stands out particularly well either. I think the game could have been really great if it was more original and creative in all regards. But even with that as an issue, the game is still pretty fun.
