In college I played Nethack. Then I moved to Moria. Now I stick to playing Angband.
The latest game I played today was Synthesizer. The web page had some ads on it. Maybe I should go click and make somebody some money? There were several versions of the game for different operating systems. I opted to play the web version.
The maze is in the bottom left hand corner of the screen. Two enemies engaged me in combat at the same time. I guess the squares with patterns in them must be the walls. Weird sounds were going on in the background as I played.
There was a "Pattern 001" label near the maze. And there were a whole bunch of controls all over the screen. Damn it. This is a game where you must read the instructions. Otherwise you are screwed. Somehow I think you must make good music in the game. Not sure how that affects the roguelike battles.
