I am a huge fan of Tetris and this just brought me back to the traditional game with more and creative visuals. It forsure brings the soul of the game within a gameboy! The pixel art very nice in how each gem is represented! Lovely work with the music as well, works well with the pace of the game.

It took me a few tries but I forsure got the handle of the game and when to get combos. I think if there was more time, it would be a perfect pace. 

Overall the game was Amazing Graphically without being unnecessarily complex, and the Soul of the game is very gameboy.

BUT, the game is very complicated to play for what it is, I don't think you should *have* to read the description to find out a core mechanic like gap hopping. and there is one bug that in effect deletes a gem you're playing with. All alongside being too fast from the onset with the sheer quantity of gems you have to work with.
There is the basis of something really strong here, and as I said it is graphically impressive, but it would need a lot more time in the oven.
