I suspect I died to being forced to take 78% knockback reduction twice (both doors had the same drawback). A lot of my damage was from rings of knockback damage combined with the sweeping spear attack throwing spears off the ground and the divine armor knockback. It seems like that's probably set because both times it was a boss fight. On the actual level I died on it looked like there was suddenly a solid field of skeleton enemies over the entire map, but I assume that's because my damage output was too low and the second enemy wave spawned while the first one was still taking damage.
Regarding what I didn't like, I'm not a huge fan of the controls, but I'd say its fine overall.
I really appreciate the feedback! The skeletons spawn a skull on death and then you need to hit it or else the skeleton will respawn and it is also quite tanky so it's not a fun enemy to face if your damage isn't that great. I will think of how to change it in the future. Also i will make it so that negative modifiers cant be the same.
