For a game that didn't have much interactivity (no offence intended) I found Children of Brinn to be very enjoyable. I put credit into the fact in how well the story and the characters are written out, their back stories match their personalities and experience/knowledge. Although the areas that you had to traverse through had several different outcomes, I can't help but feel that it was short lived, the best ending you can get (where entire party survives) is insanely easy and quick to finish, where as the hardest, would be if the only the berserker joins the party, mostly based on the fact that you have much more options and chances to screw up.
While I do like the variety of choices you have, I feel that its redundant to have any choice you make end in a complete wipe out, only diffrence is how badly. While I do find it interesting, I think you should at least have a chance of digging yourself out of the grave you stepped into, just with some injury or a more negative ending, your time would also be much better spent on investing it on branching the story into more pathways then into a short branch where you just die in a different manner.
On a personal note
I did see what you were hoping to do with this, but never got around too for time and what not, considering that everyone had an inventory (but only 40% of the characters get 1 item if ever)
In the cave as well, considering how well the Beserker or Guardian paths are written out, it seemed like you had something major planned for the original party, but cut it out for some reason, compared to the other stories it just seemed really lacking, but considering this was just an experiment, I'm willing to let it slide in score.
I hope to see if you have any more adventures planned for the Children of Brinn in the future
