I enjoyed this take on programming the movements out gameplay. Even though the robot continually moved, only pausing every third movement, I still had to build a plan out and execute it. I know it was to fit within the theme of 10 seconds, but at times the 10 seconds felt generous and didn't make it too difficult. Kind of reminds me of a board game I played with my kids when they were younger called Robot Turtles.
A couple of things I noticed on the second level were that the second coin in my route was not picked up since I placed a 90deg rotation on the same tile as the coin. It seemed my placement took priority over the coin pickup and the pickup just didn't happen.
Additionally, on another play through, I built a different route so the coin would be picked up, which lead to me accidentally placing the incorrect 90deg rotation while I was at the top of the room. When this happened the bot turned north and moved through the wall and walked out of the screen. Didn't think that was intentional, but it did game over as soon as it got off screen.
For the two 90deg turns, I think visually you might want to try making them different colors or more variance between them visually. Once you have a more than a couple of them placed down, they look so similar that it's hard to process the path your building visually.
I think this could be developed out into a decent game post jam. Good entry overall.
