I can get halfway across the next screen, and then I get transported back into the bedroom. It happens if I go down or right. So I can't play it at all. I tried both Firefox and Safari, and it happened both times.
Do you touch spikes because when you touch spikes you die also I dont have Firefox or Safari so I cant tell you if there is a problem with those versions. Now that I think about it I probably should of added a death animation it probably would of been more obvious.
