I feel like there is an idea here, but the game is just not "readable" as in, I have no idea what to do. I got to level 4 before giving up (the one in your fourth screenshot). It's very confusing that the blocks can both go on the board and below commands. When you pick them up (and it took me a while to figure out you were supposed to click those) the board is highlighted with squares. To me, this immediately reads "Drop here". But that's not the case for the first level and you're supposed to drop under the commands. There's no way I would have gotten it if not for reading you comments. After four levels, I still was not sure what "INV" did and after experimenting a good amount, I just gave up.
I like the polish and the concept, but the game itself is just too hard to figure out.
