This was actually a really good game, and of the "2030" games I've played, it's the one that seems to do the best job of eliciting that 'future' feel. The story is actually quite good. Also, what earned it four stars from me was that the gameplay was quite unique, especially the rain in the last level. That was quite innovative, IMO. I really got into the robot's point of view with the constant need to scan and manage energy.
There was only one major bug I hit, which would usually have been serious enough to make me give up on a game, which was on the first level. I'm not quite sure how I caused it, but during one of the tutorial pop-ups, I think I clicked or right-clicked at the same time it popped up, and the game completely froze at that point. I had to reload the web page to restart it. I guess I was intrigued enough by the premise of the game to bother restarting. Glad I did.
(Actually, on replaying the first level to remind myself about this bug, I noticed another quite major one. After clicking Play again (after completing it once), I'm not seeing the outlines of the 'a dump of discarded things' objects anymore. They are completely invisible, even after a scan.)
Aside from that, relatively bugless.
I think I won't quite go five stars because I think it could be a bit longer or more fleshed out, and also because I thought the story ending was a bit of a downer. :-( But considering it's for a contest/jam, I'd say fantastic job! My favourite so far.
