I'm so glad you figured out how to fight the shadow knight! (I actually pictured just an animated suit of armor being puppeteered by shadows but calling it a knight is cooler ^^.) I was really worried no-one would progress to that point.
I spent a bit too much time on the character render(I don't draw characters very often,,,) and when I placed it on the HUD, it felt slightly off at first. It's nice that you appreciated it! There's a couple more enemies unimplemented but the Living Armor and the Lighteater(Bird) were the ones I focused on the most because they seemed the coolest.
Thank you for playing my game and experiencing it!
