The 'Tree' in this game reminds me of an Annual Erioganum or Wild Buckwheat plant. They grow a rosette of leaves, then quickly grow an umble of tiny flowers which dries up and breaks off after the flowers produce seed. The umble then bounces around in the wind, scattering its seeds.
The first time I played the game, I did exactly what the 'eye' said and didn't do anything just sat there without touching the controls. Was interesting wondering what the eye would do next and if the game would start a tutorial or something showing me what I could do. I guess I 'won' the first play through.
When I realized that the game wasn't going to tell me what to do in terms of controls, I started playing around with the mouse and keyboard in the second try at the game. I enjoyed the opening level and the next one after it, enormously. Found myself actually laughing with surprise at what hitting the arrow keys did and especially when I figured out that I could move about more or less on purpose with certain keystroke combinations.
Made me think of the 'Tree' as more like an undersea creature - one of those things that has properties of both animals and plants.
I was really enjoying experimenting with the game until I got to the next level with the spinning saws. Seeing the 'Tree' get chopped up and starting the level over again was more frustrating than fun. I think I'd like it better without the saws and instead with just increasngly tricky terrain to deal with. Was enjoying how the game seemed to be totally different from most games and wasn't about running away from monsters or killing monsters, was just about experimenting with what you could do. You could maybe make a second version in which the 'Tree' is never chopped up.
It's a very clever game that shows how great it is that there are places for indie games to be released. Something like this would probably not be published by the big companies since it is so very different from what players expect.
