Someone (who is now banned from Roblox) decided to rip The Tower directly from the PTBOOTB Rescripted game files.

You can still play it, although it's practically impossible to search it up normally.

Luckily, I found the link to the game before it faded into obscurity, so here it is:

The game is practically the same compared to how it is in the actual Rescripted game, except for a couple things:

1. You are able to control a few things in the game, which you can see being explained in the image below:
2. Despite the blue bar being in the middle of the screen, you cannot roll.
3. Usually, you can laugh clip at the halfway point of the tower with the sacrificial button in order to skip it, which is good for solo runs. However, the creator of the practice game decided to make the transparent wall (that is activated by the sacrificial button) JUST SLIGHTLY farther away from the platform that you stand on, so it's practically impossible to laugh clip through the wall.
4. For some reason, there are small green buttons at multiple points of the map which you can click, and when you do, you'll hear an activation sound and some green text appears on screen for a brief moment. Maybe there's another easter egg hidden in this game? (These do not appear in Rescripted, and are not needed to reach the top of the tower in the practice game.)
