I never played this type of game before, so for the first 5 minutes I was trying to figure out which button was for attacking only to find out I had to "lock on" to an enemy first :D
The game itself is great! I liked how you detect if we kill our enemy and die at the same time and show "mutual homicide" instead of the normal "murdered" message at the end.
However, I think the attack mechanics could get a bit of work as in some instances you would fly above the enemy and spin if you walk too close to them.
The blood-splashing sound is also spammed a lot if we never lock onto the enemy and they kill us. (A simple way to reproduce this bug is to just walk close to an enemy and wait for them to kill you)
