Thank you so much for playing the game. I intentionally made it difficult to read the clues. But can still read the clues under the candles or the peripheral vision.
There is a good chance that you might lost the cube somewhere near the statues because it has less mass. You will easily find it in the easy mode. But in the hard mode it is difficult.
But thank you so much for playing the game. I tested the game many times. And am still testing the game and will update it here once it is done.
