I'm already at the point where this become a bit laggy without Turbowarp. So, if your PC is weak, I reccomend you to use this : turbowarp.org/1087576395/. You know what to do : move (arrow keys/WASD/mobile), dash (space/quick tap) and dodge everything.
Thanks to @OnePointView for the original template and the smooth features, to @RJTheFox4 for the gears background and to @HaonDK for the boss design
