This game is an all-time classic. I somehow ended up forming an entire community simply because of this game, to say this has had a major influence on the course of my life would be an understatement. Obvious bias there due to that, but even just as a game it is so fun to just go back and beat every month or two. The level design is creative especially for a retro game and the enemies/bosses are just so fun to go up against no matter what playthrough it is. Flaws lie in the fact that some levels are just flat out annoying. Some are insanely hard if you dont have good reactions, but all around? I'd say its a pretty great game and worth the time to give a quick run through
