Huh, me and my brother (who playtested) can reach the end of levels 2 and 4 with about 3-4 seconds to spare, I'm not sure what the problem is. As for wall-jumping, I made it so that just like the normal jump, if you tap the button you do a small jump, and if you hold the button you do a large jump, and yeah, and yes, you can actually jump straight up a wall while wall-jumping. Sorry if I sounded defensive, I just think this idea has some potential and would love to fix and expand it. Also, its awesome to see another Celeste fan, that is probably my favorite Indie game! (Btw your game was great too)
