Reminiscent yet Unique
This game was quite masterful in plot.
The only thing I must point out is how the plot was started. There doesn't seem to be fateful event from which comes the dwarf's tragic fall. I must emphasize fateful. I guess it would be quite cliche for a story to develop due to fate, but wherein does the reason for him jumping off the cliff lie? Is is simply due to exploring and he was not strong enough?
*SPOILER WARNING, mates (sorry)*
I must again applaud you for the plot. Choice (or shall I say Freedom?). That's the simple entirety of the game. Most gamers, as I was, are probably not aware that they have choices in how to get back up when in fact there are.
The choice of trusting that voice and the quest given by it is the plot that is quite reminiscent of Shadow of the Colossus. The story, however, of it is the only thing I am allowed to compare your game to that of SotC. It would be foolish of me to do otherwise...
The thing of beauty in your game, if not the environment, music, and atmosphere, is the realization gamers must face in aftermath of the their first play-through and its tragic plot twist. It is the realization of guilt for trusting that voice. It is also the realization that you have the freedom of choice in this game.
I would give you a 9/10 for how you initially deliver plot, but the entirety of the game makes up for it. This is the only game that made me both consider and actually create an account for the sole purpose of writing a review.
Excellent Job, I hope to see more of your work.
