I decided to take Stickless, add some stuff, and make a version of Cuphead. Move with the arrow keys. Shoot with z. Jump with x. If you press x midair next to a pink object, you can perform a parry. Touching red decreases HP. Lose all HP and you die. Shooting the enemy enough will make it die.
Besides some sound effects, I made everything by myself. If this gets enough love and attention, I might make it into a full-scale project.
