hey thanks for testing :) there seemed to be a bug with the enemy damage indication on itch.io . If the enemy's hit they should be colored red and the dmg you have done should pop up. The coloring should be fixed now :) so if you want to try again, it should work now :))
I can tell you from playing myself, you do make damage, it takes a while though. If you combine spamming space and left click, you basically stun camp the Insects(/Skeletons?). If you get lucky, none of the bow people get close, or get close enough to be stunt with the melee people.
