Thanks for the positive feedback. I'm also very pleased with myself every time I mow down large groups of enemies, but it used to completely tank the frame rate! It's doing much better now after some performance optomizations.
I'm not sure whether I'll add many more enemies, but I do want to change and test different combat mechanics and try to improve balance.
This is a prototype for the game I do want to make, where I will have more content.
