This game was very good, I enjoyed it. I have some recommendations that I believe would make the game easier for the player to understand. First please include a tutorial level, I didn't realize that the black panels are not trasspasable but until thorough analisis of the mice behaviour. Second, add an achivemente system, I would like to be rewarded for things like finishing in the least time or with the least arrows. This game is good and enjoyable.
I recommend you play this game.
