Hi Lazlo, thanks for reply. I already solved first error (just being moron that doesn't red documentation more than once- I used one variable twice with hope it will work :D)

Also, great thanks for Giovanni Sales - great idea, will try it tomorrow morning; if it will work, I can make time rewind like in Prince of Persia, that works only for a bit of time- not "let's run through level once again" ;]

I hope I won't bother you with that kind of stupid questions. Thanks again, I really appreciate your help!
