I really enjoyed this game it was quite fun. I feel like there were some small issues like:
Being able to pick up and move objects after placing them would be nice.
The colldier on the buttons at the top of the screen is a little small.
After picking and dragging an object right clicking would return it straight back instead of having to click off it then right click on it. It felt like there was a lot of latency in the controls but that might just be the web browser version of the game.
Nice work, i look forward to your next dev log!
