I recently started replaying this game, which I have finished before with no problems (albeit on my old computer), but this time I keep getting stuck at the third brick leading to the vent in the mine. no matter how much i jump, even when it looks like I should be landing on the brick, I fall straight through it. I am unable to triple jump at this point in the game either, but I believe that part is intentional. I've tried restarting the scene at least five times, restarting steam/my computer, but keep having this same issue, which is super frustrating since I've almost reached the end!
