5/24/2022 Game update

This game has been finished for a while, but after recieving some feedback from the judges of the VGDC awards, I decided to brush up some parts of this game to make it feel a little more complete and improve the user experience. Here are the patch notes:

• A zombie counter has been added on the HUD. Now players will always know how many more zombies they need to defeat in a given level.
• The end of the level now has a beacon reaching to the sky with a color on it displaying whether or not the level can be completed.
• A few new easter eggs and secret items have been added to utilize the mirror mechanic a bit more and align better with the tutorial sign about some things only being visible in the mirror.
