Gex: Enter the Gecko/Aztec 2 Step

This likely appears when you have 4 red remotes and 4 silver remotes.

Collect the gems in time
There are 50 gems to collect. To complete the level, you need to collect all gems and the remote within 3 minutes.

The first room has 25 gems, all around the sides of the room. There are also two floor buttons underneath two gems that need to be pushed.

In the second room, the gems are hidden behind walls. Jump onto the floor buttons in the front corner and middle to retrieve all remaining gems.

Once all 50 gems are collected, jump down into the now-open pit, and get the remote.
