Do you include one of the following "jump buffers" (or whatever you call them) in your games?: - "ledge" buffer (a few frames to jump after falling off a ledge). - "bounce" buffer (you jump again immediately after reaching the floor if you pressed the jump button when falling). For my current WIP game I'm using a 6-frame ledge buffer (60 fps), anything else feels slightly off (of course, YMMV since it depends on the playable character's speed, hitbox, etc). Haven't implemented a bounce buffer yet but I'm tempted to do so (probably limited to just a few frames). Are you using other kind of buffers too? (not necessarily related to jumping).
