Pretty fun! The physics were a bit silly but that was part of the charm I think. I couldn't ever un-flip my trailers once I flipped them and the new ones were always flipped too lol. I would have been nice to have an accelerator or have a faster and slower driving mode maybe? And it was sometimes hard to find my way back to the base once the crystals were generating far enough because of the fog. But there was something satisfying about the trailers emptying slowly and aligning your trailers so they empty.
