Old school 2D controls

Hello guys.
I am working on a 2D platformer and I want to give it the feel of the old school games. So basically, I am looking for controls that do not have any gliding.
Tutorials would be very welcome as I am still quite new to unity and coding overall.
Thanks in advance ^.^

I feel like the Unity Input System will do exactly what you want, if you configure it correctly.

It can’t handle every variation - at least it doesn’t seem easy to make it handle every variation. For instance, I haven’t easily found a way to hide from the rest of my code whether input is coming from a touch interface or from something else.

There are also very powerful and useful controller systems available from the asset store for what I consider to be a very reasonable price. They usually come with pretty solid tutorials, too.
