The fly weapon:
- The explosion always happens when the damage over time ends
- When the explosion would kill an enemy during its damage over time, it explodes - this makes it way more useful if you hit an enemy and don't finish it off and swap to another weapon
- No longer has a limit of flies before it explodes - combined with the above its is more consistent and understandable - it's now much stronger against high health enemies
- Is louder
- Has a sound when hitting enemies
Also level 1 tells the player about dashing on hard mode.
