This one was different, no so much a game, but as you say, an interactive poem. What a vibe!
The visuals, music, and design worked well together to create a mood. I did think the music was a weak link in this regard, i liked it, it was just a tad too repetative and didnt loop nicely.
Otherwise, thank you for the message and poetic interpretation of the theme.
If I were to suggest anything, I thouht the ability to ascend aswell as descend was interesting, I thought maybe u were going for something celever where the text would read differently if you reversed it, and while im not suggesting you do that (I suppose it would be a little corny) I wonder if there isnt something interesting that could be done with the ascend/descend mechanic.
