Great one! It got me wetting my pants, well not literally, but yeah. The agony is there. Almost perfect, but one point in gameplay. Pressing the button too fast made my wrist hurt... Point for extra mappings. WASD and KL. Not that this is my thing, but I strongly believe d-pad on the left, buttons on the rights is part of the gameboy soul as well.
If you’re talking about pressing the buttons to open/break things, the action is to hold not mash. I realize this isn’t the clearest thing in the game though (if you skip over the objective screen before the run) so that’s my fault! Absolutely, I added WASD K/L and controller mappings just for that option, I personally use WASD K/L. :)
