Arya - Roguelite Platformer basis

[STM1993]

The midair inertia would be pretty bad for precision jumping (as I found out trying to land on single tiles and later half a tile).
You could make the initial tapping of walljump slightly lower on height and instead emphasize how much to hold spacebar, or simply design levels to not have only 1 tile of space - it is difficult to jump back unless you drop to about 2/3 down a tile (based on character's head).
I like how the camera changes size accordingly, and I've always liked platformers that have small characters but large visual range.

Also gonna point out this is possible to stage 3:

At this point its pretty much how you plan to design your levels to work with the controls, though currently bigger levels and less precision (minimum 2x2 spacing) would be preferable.
