A pong / breakout game is a surprisingly original idea for a roguelike. I kind of like this mixture of classic and modern designs. The visuals are all very minimal and clear, and I like that you used a background color other than black, which makes the visuals feel more relaxed and original.
One glitch(?) I did encounter is that, if I push the ball straight up, it'll suddenly move diagonally the next turn. Which hurts strategy a bit and can lead to some unexpected movement.
Overall, this is pretty nice. Using random doors was a pretty clever way to convert this from an arcade game to a roguelike.
