Instead of defeating a boss or getting to certain spot, in this game all you have to do is collect achievements. All 25 of them. My advice is to take things slowly until you at least have 4 or more achievements. There is a way to do all achievements. ONLY IF YOU ARE ABSOLUTELY STUCK, click see inside. There are no instructions other than these. The game is fairly self-explanatory.
Idea gotten from Achievement Unlocked, a similar game where the whole point is also to get achievements. Any comments saying exactly how to earn any achievement WILL be deleted. However, any hints that don't spoil the achievements can be kept, depending on how much they say. 1.02: Small changes in preparation for big update. 1.01: Added one more achievement to the game! 1.0: Released with 24 possible achievements.
