Level 14?! – Fireboy and Watergirl: Online Review

Love this game but confused how I’m supposed to pass level 14. There is a gem hidden underneath the staircase and I cannot access it no matter how hard I try. Is there a secret entrance or something that I’m missing? It won’t let me move onto level 15 until I get that gem so I’m getting very frustrated. Someone help SOS
