Never mind looks like I've found a solution by hitting the Level X achievement button to enter the level although It still doesn't work and I've tried It on two browsers (Google Chrome & Microsoft Edge).
My bad seems like I can't see it although can someone help me with something? Level X seems to be un-playable for me and I've completed every other tunnel that is available to me at this point in time. Can someone help with my issue If so thank you very much!
