Love the look and feel of the game! And a very unique premise.
Suggestions:
-- Polish the Trailer
-- Flesh out the Itch page content
-- This quote from your One Pager may be a better hook than the current tweet? Maybe try A/B roadtesting for clickthroughs from both?
When The River Runs Dry is a narrative driven adventure game, complete with mystical water powers and a quirky collection of animal friends -- all to be found on a journey to the summit.
-- The One Pager Press Kit is really handy. Personally I think an easy to access Google Doc like the Indie Legion Press Kit Lite is really good for quick info gathering, with links to other content being very useful. I haven't verified this with Content Creators so it's just an opinion but if you have all your info anyway it can't really hurt to have that accessible.
