-Flashing:
*Remaining flashing time is now increased if attempted color to flash is the same as the color a creature is currently flashing (rather than a separate coroutine for flashing starting, causing inconsistent flashing lengths)
*Flashing a different color will keep the creature in their "flashing" state while changing the color and resetting (but not increasing) the remaining flashing time
*Generalized how changing creatures' colors works
*Default colors are now set to the color the creature has when it spawns by default
*Fixed flashing always resetting creatures' colors to default
-Added functionality for creatures to communicate to bullets if they have been hit by them
-Fixed bullets triggering their DestroyOnHit function continuously until they are actually destroyed
-Prevented weak points from attempting to trigger enemies that no longer exist
-Fixed weak points only detecting triggers once
-Fixed Squzes occasionally spawning in the ground on Wave 18
