"Z" place a dot
"X" punish Blocks a way
"arrow key" and "WASD" move
You start with 4 blocks.
In the starting area there is 5 more Blocks before getting the 3rd dot upgrade.
And 5 more Blocks after.
Their is a thing in the large room you start in that take the Blocks (It has 24 slots) as far as I can tell it appears at the same time as the text.
You can get out of the staring area in the room past the door that needs three dots.
Moving east 1 there is a L shape obstruction.
Moving east 17 and north 11 there is a shop with sliding bar of icons that look like ix's art (just follow the path) and use doorways) I could not work anything else out.
Moving east 2 and south 14 there is a Block. I don't if you can get back into the starting area.
Around the north west (above the large room) their are more obstructions. I could not find anything else.
Moving for around 10 minutes north, east, west and, south* (*: I have not tested) you will end up in space, their is a star puzzle that I think could be solved with a 4th dot.
I not too smart so hopeful this help someone else and also not against the spirit of things.
