Added final two levels

Seasons greetings from the devteam, bringing you a huge update

• The spiders were complaining about RSI from attacking so often, so we are allowing them to attack less frequently.
• Difficulty scaling has been compressed, what used to be difficulty 25 is now difficulty 5.
• The damage formula has been corrected to also scale up monster damage with increasing difficulty
• Boss monsters have been given a health bar on the top of the screen for their dedicated service to the cause. For reference it was a choice between screen space or a cinnamon
• The "press any key to skip" should now work properly in most cases
• Some monsters may be empowered. Empowered monsters are considered to be 2 difficulty levels above normal monsters and are also authorized to break the rules at their discretion in order to resolve customer complaints.
• Added a castle level (level 3)
• Added the placeholder nightmare level (level 5). This level is not completed.
• Added a zoom feature (mouse wheel)
• In order for you to keep track of who is carrying whom in the party, you now have access to your party members health bars.

Also consider using the itch.io app to update our game. It will cut down on the amount of data you need to download, the patch came in at 235 MB instead of downloading the entire 761 MB project.
