Large number of tweaks and quality of life changes

Note: I am currently working on a revamped version of this game from scratch. This game was made in a limited time period for the Brackeys 2020.2 Game Jam. The changes are mostly tweaks and quality of life improvements, but feature no actual new "content". This was done as to not steer away too much from the original game jam submission.

List of changes:

• Slightly increased attack range
• Slightly increased spectral damage dealt through attacking
• Massively increased damage on dash
• Lowered cooldown of dash from 5 to 3 seconds
• Lowered cooldown of rewind from 10 to 4 seconds
• Lowered time rewinded from 4 seconds back to 2 seconds back
• Fixed bug where redundant piece of code would count spectral damage as poison, and very slowly kill enemies
• Added a tip that tells player dash makes them invincible
• Made early platformer section easier by adding more tiles to platforms
• Added a tip that tells the player they'll hear a sound when the door opens
• Increased the volume of the "door open" sound
• Made it so enemies that are in the same horizontal position as player only jump when below player
• Put the number of the level on the screen
• The screen flashes red when player takes damage
• Fixed small visual gaps between blocks
• Added extra optional keys
