I like the core gameplay of the game, but after getting out of the "first closed room" it is a bit unclear how to leap over that one larger gap. Also it is unclear to me if LMB and RMB are not supposed to do anything from the beginning or if attacks will be available later on. But the game was fairly punishing and I honestly had motivational lacks. I do think thought that the ledge grabs are better than most people said. The inconsistencies come much more from how the environment is build, e.g. there are some edges which are only a few pixels off from being grabable which is confusing for players.
Still I appreciate you effort very much: keep going!
