I liked it, but I'm not really getting the "ruin" feeling. It's a different but good approach to a memorization puzzle game. My tips for improvement would be to use another font for the text or enlarge it without the black background so it fits the overall style better. I'm not familiar with monkeyX so I don't know how their text system works.
I only figured out how to exit the chests by reading other comments first.
And from the sound of it I don't think English is your first language so I didn't hold that against you, but if you'd like to polish your game further after the game jam I'd recommend having an english-speaking native help reword the text. But it wasn't so confusing as to hurt the ability to complete the game, I did all 3 levels.
