Thanks for the graphics praise <3
On the graphics side. I have basic tileset in Photoshop and I made a script that saves all said bricks with current settings to a folder. All I needed to do was change color or wall type (brick, horizontal panels, etc) and run the script and wait about 30 seconds and I get all the bricks I need with that color and wall type. We even had to ditch one wall type because we went over the itch.io file limit with over 1300 files. The game currently has 840 brick sprites and 26 mortar files.
The crane and bulldozer are both drawn in illustrator and brought into Photoshop to make the actual sprites.
I used to work in a newspaper as a photo journalist, photo editor and graphics artist for 19 years. so my workflow has evolved to be pretty fast with familiar programs.
