Chasm is a fantastic Metroidvania with a gorgeous 8-bit art style. However, default keybindings feel terrible and should have stuck to the tried and true WASD.
You can rebind them to your prefered layout, however.
My Biggest Issue.
Controller support is haphazard at best, and my Dual Shock 4 controller was barely recognised by the game, button inputs would be entirely ignored, and directional controls were sporadic at best, trying to even walk down a ladder was near impossible.
