I enjoyed this! It felt like a bit of a time race on some of the levels to get your pieces placed in time. I think some ideas were a grid and pre-planning, a grid would be helpful for sure, but I think pre-planning would change the feel a lot. Since then it'd be more about perfecting your solution instead of trying to speedily lay down modifiers. Maybe as a substitute you could use keybinds to drop them on the cursor for less mouse movement? Good stuff!
