Not bad! .. nice concept of making us have to look at many angles to figure out where is where. Though you could have made it a bit more challenging based upon the sheer size .. plus having it difficult to get up / down stairs due to tight squeezes is unnecessary cause you have ample room.
Well,at least there is no FD so that is good... uuhhmm,too many red bricks to my taste... the gameplay is quite easy but not bad... thanks for sharing @Lucky
