Level 100?! That's amazing, thanks a lot for playing! I hope you get yourself all the skins available with 100 coins :)
I entirely agree with all the feedback. Regarding the mouse focus, I realized I should have done it while recording the gameplay trailer, 30 minutes before the deadline :(I agree a lot with the enemy variety/amount and probably have more and more varied mutations.
Regarding the no hit issue I need to figure out how I fix it, let me explain with an image: https://imgur.com/a/nqDxtnj

The hitbox for the cuts/damage is at the tip, and that creates a big gap when you have scaled the sword. I have the hitbox at the tip because, in my mind, a perfect cut with the blade is from the center to the tip, but I agree it can feel like a bug. I'll try tweaking the hitbox to be bigger and more rewarding. Appreciate the feedback, and thanks for playing. <3
