Overall a fun game. The puzzles were interesting, and the graphics were good. Only two pieces of feedback though:
1) Never force the player to move with the arrow keys. Why circumvent the convention of using WASD for movement? First, the player has to think where to move, which is normal. However, because of the lack of movement with WASD, the player now also has to think how to move.
2) I personally felt that the music didn't fit in with the theme and tone of the game. Towards the start it (i.e the music) has a pretty neutral tone, yes. But as the game progresses, the music develops a playful kind of tone, whereas the game wants to tell this serious story about this robot that feels trapped.
Other than that, the game was great. I really liked the menu-screen. Good job!
