Thanks for your detailed feedback!
Yeah it's a little bit confusing. That feedback I read a lot. Sorry you had to spend so much time finding the waterfall entrance... I will work on Clarity / Tutorials ASAP. That's why playtesting is so important.
And yes the idle gameplay loop is also missing some things and doesn't feel as satisfying.
Good Point with the night cycle. In the web version I feel like it's much darker than in the downloaded version. I will fix it as well!
