This game doesn't hold up well with age. Camera is zoomed in too close to be comfortable when platforming, which is made worse when dying causes you to lose all your upgrades. Not that it matters that much, since the enemies usually aren't that dangerous compared to the platforming.
Do I rate this good because it is a 15 year old game that I played as a kid? Or do I rate it low because of it's flaws? I'll put it in the middle.
