Difficulty rebalancing patch

The game has been out for a month now and I've decided to make some changes to help out with the difficulty based on feedback and some of the things I've seen, the changes are as follows:

General changes

• Increased normal difficulty health from 3 to 4

• Slightly decreased the darkness in dark levels

• Increased the player's vision radius in dark levels

• Increased the delay between waking the worm enemies and them attacking you

• Increased the player's friction and acceleration on ice levels to reduce how slippy it is

Level specific changes

• AdjustedW2-3Increased the time platforms stay up by an extra 0.5 seconds across the whole level
• AdjustedW2-4Changed some of the enemy spawns to only appear in hard mode
• AdjustedW2-5Decreased the amount of time the lava geysers are active so that's more of a gap to get through
• AdjustedW3-5Increased the amount of time it takes for the enemies to start chasing you after the lights are turned on and decreased their chase speed
• AdjustedW4-3Increased the height of the alcoves where two glowing squid enemies appear to make the timing to get past easier
• AddedW4-4Added a slope to an alcove to make it easier to jump in to
• AdjustedW4-5Slightly decreased the max speed of the fish enemies that chase you

Hopefully this will make the game easier for some and make world 2 less of a wall for many
