Croc: Legend of the Gobbos/Secret Sentinel

Here you are at the final challenge of the game. The central part of this room has no floor, while on the four sides there are compartments where you will find a gong and two crystals. The crystal boss floats in the center of the room and will attack you by firing lightning bolts: try never to stay still in the same spot, or you will be hit. There are also crystal platforms that revolve around the boss and that you can use to move from one compartment to another. To defeat the boss, you will need to synchronize all four gongs. That is, you will have to hit them quickly one after the other, before the vibration emitted by the first gong hit is gone. If you take too long, you will have to start over. So at the beginning, turn around and grab the two crystals near you to protect yourself from the boss's attacks and hit the gong. To move from one compartment to another, it is not recommended to use floating platforms, as you would waste too much time. Instead, you should take yourself to the corner of the compartment and from there jump directly to the one next to it, repeating the operation. With this strategy, if you move fast enough, it's not too difficult to vibrate all four gongs together. If you succeed, the boss will die and you will have completed the game 100%. Congratulations!
