Is Tack Attack a ripoff of Flappy Bird?

All my friends are addicted to a new game for iPhone called Tack Attack but I personally can't get into it, I think it's just another ripoff of Flappy Bird. Yes I know there are tons of Flappy Bird clones out there but this one is different because there's no bird and no pipes, so my friends are arguing that Tack Attack is not a ripoff of Flappy Bird. They are that adamant about it.

Do any of you like Tack Attack? I think it's a new game but everyone at my university is playing it and getting addicted… But I can't see what the big deal is. Isn't it just a ripoff of Flappy Bird, which everyone already played to death?

IPhone messages won't send to ONE person?

My dad can't message me at all. We both have iPhone 5s', however he still uses SMS, while I use iMessage. This shouldn't be a problem since iPhone's automatically switches the SMS/iMessage mode depending on the person who you're talking with. Every time my dad tries to message me, it will not go through. He gets a red statement under his message saying "Not Delivered" with a red exclamation mark.

I checked both iPhone's blocked menu, and we didn't block each other. I can message him fine. So I did some testing like deleting my contact from his phone completely. Then I tried messaging him, and I expected to see 1(###) ###-#### as the contact name on his iPhone, however I got instead 001##########. I'm curious to know if those 00 in the beginning means something. If so, how do I remove it? I did some research and it means some out of the country type of number.
