Hi everyone! I'm finally releasing the fourth update :)

Here are the changes and additions to the last one:

- 5 new levels.

- Fixed sound in some places.

- Improved visuals (I finally fixed the ugly stairs from the 3rd level)

- Improved optimization on several levels from the past update.

And that's it for now! I'm going to take a little break so expect the next update on (hopefully) the end of september. Have fun!
