Hello SES,
Great game. Really enjoying it! I play exclusively on Xbox One and have found using the terraforming tool a challenge. I certainly don't expect the level of fine detailed control you have when using a keyboard/mouse but it for sure requires a learning curve to use it well with the sticks.
One of the more challenging aspects is getting the center dot of the targeting cursor on the right starting ploygon when attempting to flatten terrain. I think it would be very helpful if the center dot of the cursor was a different color other than green. Initially it could be red,
