Very Retro
The graphics are great and it has a really old school Nintendo feel to it. As for "Aginor27"'s review saying that the free part of the game "could be a real shit part", that would defeat the whole point of the object, wouldn't it? Why make it shit if you're trying to intice people.
And stop taking offense at the payment system. If there wasn't extra packs and such you wouldn't complain. They're just there as extras, so enjoy what you've been given because it is a solid game on it's own as it is.
Best of luck with the coins system, the gameplay was enjoyable but ever so slightly repetitive. Saying that I do feel it deserves a much higher score, it's just a shame that people can't get over themselves when it comes to being the option to purchase extra features for about a dollar.
