I find it hard to point out flaws in the game. However, there is one serious flaw which is a bug. The game allows you to collect more than 20 gold coins (related to another bug), but to finish the game you need to have 20 gold coins in the pocket, and no more. Be very careful about that when playing the game. Other things some people might complain about could relate to 2 or 3 difficult jumps (but it's all about getting used to the positions of platform edges in the game), and few rather "tricky" puzzles. Also, the fact the player doesn't know where the game world ends might be a bit frustrating, deluding him that certain locations are crossable while they aren't. But that would be it.
