Simple but absolutely intriguing, with some Marble Madness-ish flavor. Beware: Fragile Ball can be incredibly frustrating and unforgiving, even worse than the old gold Marble Madness, but if you learn to master it, it really can be rewarding. I spent as much as 30 tries to overcome level 84...just sayin' that. There are 85 levels, and the last one hides a surprise, but oddly I found the 84th being the most frustrating one, making me rage-quit more than once. Other than that, it's a really good puzzle game knockin' your head against!
