Thank you for the feedback, I'm glad you liked my game!
The cursor not resetting is actually an intentional feature. I did consider making it loop back around at first, but I found that the risk of overshooting adds tension and forces the player to think carefully before pressing the button, which aligns with the point of the game.
This mechanic also adds depth to combat. It makes the player have to decide whether to play offensively and risking overshooting the dodge for the next enemy attack and leaving themselves vulnerable, or play defensively, prioritizing dodging but potentially missing attack opportunities. Similarly, spellcasting requires precision and control to avoid overshooting key inputs.
I found that the linear movement gives the one-button mechanic purpose, elevating it beyond just being a stand-in for mouse clicking.
