I really enjoyed what I saw from the game. I bought it myself and love the general design.
However, I have to agree, it looks like this game hasn't been updated for a very long time. It's kind of disheartening... Aside from the incredibly short amount of content, the camera also seemed to be bugging out in a way which really detracts from the main thing which a pretty 5 minute game has going for it: the visuals.
If I had known that it had been so long since the last update, I wouldn't have bought it. Which is disappointing, because I think this game has so much potential to be great.
