When you enter the game there is no explanation about what is going on, I saw a lot of information on the HUD but couldn't tell what they represent.
Getting closer to the first "ovals" which I guess will be people, my first intuition was to press the left-mouse button but nothing happened, them I tried again with different buttons ('E', right-mouse, space, enter) and noticed that the numbers changed on the HUD: +10 points at the Happy face on the left and some numbers on the right.
I clicked with left-mouse pointing to the container and it got smaller until disappear in the middle of air, so I kept doing it with everything that I saw: more containers, piles of earth, tress (they have no action) and more "ovals/people".
My guess so far was that I had to collect everything that was on the way and click on the "ovals/people" because the HUD always changed and the points for the happy face were growing. At this point I couldn't access one of the people because (my guess) is that the collider for the tress are really big (probably taking the area for the leaves too?).
Just finished walking around the whole map, apparently I collected everything and nothing happened. I pressed ESC and discovered an interface with some more information. It explained a little bit more about my goal, the tasks are still not implemented and I could see that the containers that I collected are on my inventory. On the Help menu I found some interesting information about Building Mode, I tried and nothing happened, another box with some icons appeared on the HUD and no explanation on how to use it. Tried to do something, couldn't. I'm not sure if there is something implemented for Building Mode or not.
What can I say is that it's super hard understanding what you are supposed to do, the icons and numbers on the right of the HUD makes no sense at all, at least for me. I know that it is not even an alpha version of the game but I would at least show a GUI Text or something right before the game starts explaining very shortly the commands, what to do, how to access everything and after the player hit any key on the keyboard he can play the game regularly. That can help us to test the game and know what is going on, what was already implemented, the kind of things that matters so we can explore and help giving a better feedback.
Also I asked my girlfriend (she's a casual player and programmer) to try the game and write about her experience (shown below)
"The purpose of the HUD device in the bottom right corner is unclear. It was confusing and I was unable to figure out what it was for. Additionally, finding the menu that contained the information about the game (what is going on, what you're supposed to do, etc) took a while so I spent a lot of time initially just wandering around being confused about what I should be doing. Build mode was frustrating because you couldn't do anything, but this is likely because that part of the game has not yet been implemented. Also the HUD in the bottom left was confusing to figure out. It was not obvious what the information was about. It took a lot of experimentation to discover that the top line had something to do with finding the people/blobs and the second line was related to finding the crates. The third line with the clock did not seem to do anything, again I assume it just has not yet been implemented.
More information about the stage of development and plans for the future would be helpful. It is unclear what the final vision for the game is which makes it difficult to work with. It would be helpful to know what all has already been implemented and what is going to be implemented soon, etc."
