I like puzzle games but I am - unfortunatly - very bad in finding out, guessing and searching. So, not critcizing your game, but me, myself, I simply cannot do it. I liked Riven (Successor of Myst) and liked it, so drawings in books or on the wall are really great, but I dunno, I'm too dumb to even finish Level 1. I could make the box hide, also be inside the box, I see the door opens when "far away" and closes when the eye sees me (I guess). Shooting the eye surely does not help, I wanted to block the eye sight (by moving something between), but I cannot move the black box, even though I used the right "moon" for that - there is pull and push, I got it, but neither clicking, nor dragging... nothing really pushes or pulls this box in any direction - not outside the box, not inside. I'm sorry, I would probably just die in this room. I don't know what to do. I would like to say, maybe you should leak the how-to of Level 1 here, so people like me could understand and then - hopefully - try the other levels, BUT on the other hand, there are already people here you did manage to do it. :shrug:
And then there is the missing fullscreen and/or bugs in the game: Sometimes moving the mouse right does not work (while left does work). Sometimes, I accidentally scroll the page - I don't know how it happes, because I hardly get the mouse out of the game (using ESC sometimes does not work). I might try F11, but only when I get new ideas what else to try.
So, again, not your fault or your game. Maybe, I'm not fit for it. But also, maybe some easier levels would help and let the players start with less frustration. The challenges could come in levels after this simple ones!?
Anyway, cool effort and be proud you dared something and did not create a game that already exists in 1000 variants already!
