Pretty good game, 4/5
I played it on Windows 10, Opera Browser
My issues will probably echo with the people in the comments already, but here we go from worst to not so bad:
1. Lag, this game needs some optimization
2.No bigger zoom
3.No blueprints
4.Buildings should be available in like a backpack or something, a lot of time in the game is wasted moving back and forth between your building storage space and where you want to build, exasperated by lack of bigger zoom
5.No building rotation
6. Clogging, this might be a skill issue, but in my opinion the machines shouldn't stop working if there is something left in the output, it should just overwrite whatever was there.
7.The ability to move progress between the browser and the installed version.
