I sat for a while trying to figure this one out, and there's quite a bit to this.

I did have to scroll up and down a fair bit to figure out what did what, but then at 64x64 there's not a huge amount of space to try and explain within the game itself!

My main annoyance was I think that the cursors should rotate the robot first, and then move in that direction if it's facing it. I kept having to backtrack a bit as I pressed left to "turn left" and ended up "turning left and moving one left"

I managed to get some factories working but I didn't manage to get the door open.. think I'll come back to it later and have another go when I've a bit more time to sit and think!

Honestly, I don't understand what I need to do here. I can move my little robot around, and I worked out that I can pick up the little collections of 3 rocks (?), and when I put that collection back down again it seems to have turned into a red block with an exclamation mark on it. But I don't understand what's going on. This feels like it could be a really quite nice puzzle game, but the initial hurdle to get into it is too high. A set of tutorial levels which introduce the concepts would be really, really useful here. And this has, I admit, suffered because it's part of a game and I have nearly 100 games to review, for which I apologise. If this gets some tutorials, and once I'm in a little less of a rush, I'd be happy to play this again and see how it feels!
