Hey, I'd say that I quite liked the game overall, and the visuals are really pleasing to the eye :) Especially in combination with the lighting.
When it comes to the gameplay, I did enjoy the puzzles, although the battery kept me anxious all the time that it will run out (and I assume put me to the start of the game?). There are two bugs(?) I have noticed though. First, in the pushing boxes sequence, you can actually put a second box on the same pressure plate, and it makes it disappear. Due to that, I couldn't complete the puzzle. Secondly, if you leave the text open during this sequence, it seem not to take your battery down, but when I "spaced" through the text box, it started draining again.
But as I said at the start, the game is pretty good, and it does feel polished :)
