Eat the Cake! by Little Pwnie

I’m stuck…assistance please.
OllyDgb used to gather ESP and EAX have to CMP as same for the program to run… enter 10 digit pass which can be anything… then asked for 15-digit pass.
Can someone please hint how I can find the code which is executed when the Input I enter at this point is compared/validated?
As soon as the program starts running OllyDgb will not show me whats going on… new to reversing so if this is a Basic question please go easy.
Thanks for any replies in advance.
