so after playing this mod for a good while i want to share some advice and suggestions to make the mod better and more playable in a real modpack.

make melee weapons (base swing) deal their normal damage in 0 mph because in its current state the mod makes melee weapons do 1 damage unless the player is moving

add an option that makes either the damage increases or decreases as follows in this example;
if the option is set to "only increase" the damage will not decrease with lower speeds and will always be higher than base damage, and add an option for the exact opposite "only decrease"
and ideally keep the current system no need to remove it fully, same with enemy damage multipliers

rework the current scaling meter, the current one is not too bad but confusing
1 being the lowest scaling for example a 10% increase in damage for every 10 mph
and 10 being a 100% for every 10 mph

add an option to ignore projectile speed (not in the current state) because some weapon projectiles are simply WAY too fast and deal absurd amounts of damage (for some reason medusa's head deals so much damage) or deal 1 damage like the rainbow gun
in this option only player speed will be the one that counts to the damage multiplier
TO ADD TO THIS make a similar option to boss contact/projectile damage since some bosses deal way too much damage in all modes in all current scaling options, meaning only player speed TOWARD the boss will be a multiplier

and finally just asking if you can add a feature that makes contact damage be based on how much of the boss hitbox got you; less contact less damage and vice versa.
