HOAP Bugfixes

Hello! I have fixed many bugs & issues with Hell Of a Platformer with this release, which are listed below.

-Mirror enemy (introduced in lvl 5) no longer collides with the player 

-Gravitate enemy (Introduced in lvl 8) is not longer needed to be killed to start the next wave, and dies once all other enemy types are dead

-Health bar now follows the player as intended (Though it slightly trails behind the player)

-Lowered the health of the final boss by 12.5%

-Retry no longer can send you to the next level

-Death count on level clear is now the correct size (I have just realized I never fixed the fact that the count is broken...)
