Boring and stupid.
Why does every 2d platformer have to have some stupid sad music and a "deep" storyline.
i liked it at first but the more you play it.it gets borin after a while
While the story was pretty good, the game got repetitive really fast. As for your 8th level, I doubt anyone will ever find it. The game isn't addictive enough, and while the story drove me to get all 3 "endings" (finish each level at least once with every trinket), the 8th level is WAY too well hidden (or hard to access). Leave those kind of secrets for games that are games. For pieces of interactive art like this, the key is not to put something out of reach of the player in a hope someone will, eventually, find it, but to lay clues everywhere as to where it is, leaving it as a mystery to be solved.
Overall, it was way too difficult for the engagement of the story, especially with the mechanics you gave it (Too many times have I been caught by an almost hidden flock of birds or gust of wind and pulled into the smoke. The ravens, too, are completely useless, aside for usage as a metaphor for the regrets of the past.)
the return trips are not needed and they serve no purpose.
the gameplay is ok but the story is all emotional and so boring. there were not many hard or challenging parts in the game. if this was a somehow an all emotional flash movie then it would've been great but as a game it sucks.
