Gem Star

The game is great in term of world building- ecosystem building with a massive range of choices to experiment and to deal with or benefit from other creatures, it is complex and engaging, despite its difficulty. Each playable characters have their own stats and are varied in movesets, so you basically have a lot of options. Having mentioned before, the game's slow paced play and its enormous maps makes this game rather discouraging at first, but the learning curves and the joy to explore will always be worth it.

So I would like to say this game is pretty much average. Sure it is quite hard, but that is a topic I won't discuss here. The actually reason is in terms of quality; Compares to the original SMB, this game doesn't improve any of the first game's features: no go backward, same OST and graphic. It also has a much worse and obnoxious level designs, and some extremely unfair elements (poison mushroom, warp that sends you back to level 1, hidden blocks), these elements makes the game triggering and too stressful while it is supposed to be adventurous, entertaining and exciting. At last, I recommend playing this game if you are willing to suffer and to test your patience as a gamer, or else, just don't.
