The reason I love video games. An exageration maybe but in the almost 10 years since this game has been a part of my life, I've never stoped loving it. The level design is perfect. It has a feeling of nostalgia to it which is fitting but it is also insanelly engaging and it feels like it's going for just the right amount of time. The controls are also perfect. It really makes you feel fast and the games after it more or less copied it's controls. Also the bosses are great both in terms of gameplay and fanservice especially the final boss. Really my only gripe with this game is it's length as this game is pretty short. Overall this game is amazing and without a doubt my favorite game of all time so go play it.
