Yup, it's me again!

I am going to take advantage of the fact that I am full and eager to make another trap today.

For our fourth trap, we have had to redesign the map a bit, since my first idea has been to make some kind of ax or hammer falling from the sidewalls, but I didn't quite convince that idea after trying several different combinations.
In the end, I decided on some saws that leave the sidewalls, reach the center and return.
That way there is also a difference between the mechanics of the different traps.

Here is the result:

I tried to leave the skewers in the same positions despite having saws, but I did not quite like the result...

To start I took the Gimp to make the animation of the saw.

Now for the next step, we have to make them slide from the wall, reach the end of the guides on the floor and return to the wall.
We can see the final result:

And here it is the result if we join it with the rest of the traps.

One more trap, one less step left!

Any ideas or suggestions for the next trap? Let me know in the comments!
