This might be seen as the ultimate challenge, you'll have to face boredom and annoyance to beat this game.
What do I mean by that?
Well, you have to carry around babies and shoot eggs, once you get hit by anything the baby floats around crying and you have to get him back.
The problem with this is that you are virtually unstoppable unless you fall from a high, so the first 4 worlds will be boringly easy.
The enemies don't kill you, they annoy you by stopping you and starting the horrible cry of a baby.
There's also the problem that this game is essentially a search and collect game; you can collect 5 flowers and 20 red coins in each level, I don't see the point but I guess having a 100% in a game is something cool.
But in my opinion collecting things is something I do with games i love and want to play over and over again, it can't be the purpose of a game.
It's a shame because the last lvls of the game you start to see it could have been a much better game, but a couple of lvls don't make up for 5 worlds of annoying mechanics.
So my point is, if you are looking for a similar game to a super mario bross game, this is not like it.
