Medusa is a great boss, theres only one problem though. When you use her ability to turn people into stone, its a charge instead of instantaneous/duration based, which is still fine but has some problems. One of the problems being you could actually LOOK at her and then turn away at the last second and not be frozen. Another problem with the boss, but not the petrifaction, is with firebugs. They can be an issue at times to hit with regular melee and throwing knives, causing the player to revert to the petrifaction ability. It can be repetitive just having to fall back and try to use the ability to freeze the enemy. Even though all the bosses are pretty much repetitive, it just depends on how people play the boss Because of this, I was thinking of adding another ability that either:
1. Hinder their movements or lock a certain ability (e.g. disabling jets or double jump for a given time, or slowing them down overall)
2. Give throwing knives special properties (e.g. aoe posion effect on contact with anything, or that slow down effect as mentioned above)
Overall though, shes an easy boss to get the hang of. Great job to whoever/the group that created this boss!
