Performance, bugfixes and Ghost Buff

Hi people! Thanks to your feedback in your gameplay videos, I made a bugfix update resolving some issues I've seen happening, which include:

• Falling bridge behavior being strange/missing collision with the books when they are returning
• Missing explanation that F key is used to attack with fireballs (now there is a drawing on the desk where you spawn stating that)
• Weird collision with the chairs and desks where you climb
• Zip line trigger being too short
• No indication that there is nothing behind the door (I know, that book trail is very tempting :P )
• Missing lights in "Fastest" quality

Alongside that, I also made some other changes:

• Added loading screen
• Cleaned the inputs in the Input tab of the launcher
• Improved performance in lower quality levels by disabling some post processes
• Reduced the size of the FPS counter text
• Translated texts to English (they were in Portuguese before, I forgot to do that before releasing)

And mainly, after seeing the gameplays, I realized that the ghosts were kind of pointless when you could defeat them with one hit, so I increased it to seven fireball hits, making them way more challenging when using the fireballs.

And that's it for this update, thanks for everyone that played it, and I hope you like it!

Until next time...
