Pizza By the Slice

I got questions, 

So besides the Za cards, all other cards need to be played immediately, so at the begining of the game when dealing cards does that means every player in order has to deal with their cards before drawing cards? like somone got a burnt slice, a roll out and a Za card, what happen in that case? you basically loose all your cards and hence your turn?

Also the rulebook said you can play cards to your hands when drawing cards but the Za card is the only one that you can actually keep in your hand so whats the point on doing this specially if you get the "here is your tip" card you know you will be getting a za card cause that other player cannot have any other type. Also does playing card to your hand does that mean that you just put the card you draw to your hand and end your turn?

The scoring does it mean you score 1 point per Za card you have even if there is no Pizza box card on it? or just score the ones that have a pizza box on it? 

Now i want to make some suggestions, im in no way expert on games but i hope this ideas could help improve your game. 

I think i like the idea of the game but i will change a few things to make it more interesting like instead of playing the cards immediately you keep them in your hand and use them as an attack on someone else as your one card you can play, by doing this the "pick up window" becomes obsolete so maybe make so that you can use it at any time to cancel any special ability or attack card. The "speedy delivery" will be an extra card you get to play whenever you want, once per turn, otherwise there is no point on having a extra turn if you use your turn to play an extra turn card.   The "roll out" will be attacking only the za cards the player has in their playing area, that are not cover by a pizza box.  The rest of the cards are good the way they are. 

Also if you can upload a video of a playtrough that will be awesome as it will solve many of the questions that come when playing for the first time.
