This is the Ball Revamped I remember from my childhood! It's no wonder I liked this game so much, considering how polished it is for the year it came out. The physics are far improved from the previous games, the glimmer and shadow effect on the walls finally feel like actual graphics and not some kind of placeholder, and the music is catchy (despite the loops being very short.)
If there's any one thing I'd criticize it would be the general lack of design in lieu of powerups. There's a lot of content to be sure, but a big chunk of the middle levels feel more like a showcase of different features (bombs, lasers, fire, steel, darkness, etc.) than actually making challenging levels out of them. As a result I found myself struggling the most with the first couple worlds as well as the last 5 "countdown" ones. The final boss also feels kind of gimmicky in that there's really no point in avoiding the attacks so long as you can get to the goal when it pops up. Having the player be able to react to them in some way (especially requiring some tasks to be done to make the goal accessible) would make it feel more like an actual fight.
That said, this still holds up wonderfully! Performance isn't the best on Ruffle but I successfully made it to level 55 before having to download it and play the rest in Flash Player.
