Grey Cubes is a modern take on the classic Breakout Game.

It adds lots of powerups and unique mechanics, blackholes, staircases, conveyor belts.

The levels are well thought out, I enjoyed most of the levels except the one's where you have to defend both top and bottom, but that might just be personal taste, it just makes the game impossibly hard. Luckily they are spaced apart in general and the dev is very generous with continues, only decreasing your score to get more lives.

Personally I feel the strongest point of the game is that it excels at adding 3D features to a 2D game, Cubes move, rotate, and fall over when they get hit and the physics are well done.
