Summary: This game has a very cute art style. And that's the only thing it has going for it. As another user mentioned on here, this game requires players to practically memorize the moves they will make down to the very last pixel, and that in and of itself does not require any real skill, and thus makes this game extremely boring. The movement mechanics also feel too sluggish for my liking. To be clear, I have completed everything there is to do in the game.
Summary: The graphics, sounds and level design are extremely good, almost every review seems to agree on this. That being said, I'm very surprised to see several players complaining about the controls of this game, in my opinion they are great, among the best I've experienced on iOS platformers. I've completed all 20 main levels collecting all the coins and even though I've died a million times I never blamed the controls, only my skills.
Summary: I absolutely loved this game on 3ds. Refreshing retro gameplay, awesome 3d effects, and percise platforming controls. The ios version does most of that well, except the most important thing of all: the controls. Yes, the virtual buttons break the game so bad, it warrants this review a 1/10. Absolutely unplayable. What's the point in playing a platforming game, if the controls are an absolute mess?
Summary: This game works very well on the 3ds and it manages to keep the retro-gaming feel without feeling like it's pandering to the player. surprisingly large amount of content for such a well priced game. the difficulty curve is about what you'd expect for a game of this generation... the earlier levels might feel way too easy (or i may just be seasoned enough as a gaming veteran that the difficulty wasn't as tough as it would be for a younger/less-seasoned gamer.
Summary: While it's difficulty may turn away some people (not to mention it's tad-inflated price tag), it's a faithful shooting/platform homage to NES games (also, the Game Boy and Virtual Boy bonus levels are a treat).
Summary: One of , if not the best game on the eShop right now. Fans of classic platforming will love this game. The 3D effect is used brilliantly and the game itself oozes charm. This is a must own for any 3DS owner, no doubt about it.
Summary: To start off: gamerHeaven rated this game a 1. In case you can't tell, that is a very biased score. Some of the complaints include "you end up replaying a level dozens of times until you perfect the move required to pass the point that you are stuck at", and while this a bit true, it REALLY gets easier once you start getting it down. So it's not really a developer's mistake, just a skill factor.
Summary: Boring, repetitive, short, ugly, needlessly difficult, and over-priced. There are better, cheaper games. My son thought it was boring too. Judging by its metacritic score you can make a game with terrible, repetitive level design and as long as its retro its somehow ok.
