Its a cool fun game but the 17th stage doesn't work. I press the button that is supposed to represent the sequence of numbers that it gives me (07 107017) and it does nothing. And the first hint says "Hello?" which I already got that it was supposed to be a number pad. The second hint was "telephone number" which I responded in my head with ok that is basically saying the same as the first hint but then I thought about it and thought maybe it was suggesting that the list of numbers was a phone number... Which it isn't because a phone number would have to be (000-000-0000) so its not long enough nor is in in the right format for a phone number even if you got rid of the first 3 numbers acting as an area code leaving it as (000-0000) but then it would be too long by a number. So I have no clue how to solve this puzzle if it even is possible. I would have given it a 4 star but because it was fun but because it seems to be unfinish-able I give it a 2.5 because it was still fun up until that point. (if the phone number format is different in other countries then sorry but that is the only format I know of and it doesn't fit, and I tried just putting the number in and it didn't work so idk...)
