Is there a specific reason that the mouse button is used for attack rather than using another keyboard key? I've noticed this trend in itch platforming games lately where the mouse is used for attacks that don't need any sort of aiming or anything. The mouse button is just being used instead of a key.
This makes a lot of games very hard to play on laptops that disable the touchpad for a brief time to prevent errors while typing.
I'm honestly curious why there's this (seemingly) recent fascination with the mouse button on platforming games. Are people just so used to FPS games that they use WASD/mouse as the default controls for everything? Are laptops that disable the touchpad just so rare that nobody realizes they exist, or they're rare enough to be irrelevant?
