Evil Magician Returns by Byte Knight is an adventure style game for Atari 2600.

About:

This game is based on the Evil Magician mentioned in the Adventure manual. The premise is that his dragons are now dead, so he and his apprentice have returned and captured the golden chalice. The Evil Magician (red wizard) has the ability to shoot fireballs, his apprentice (white wizard) does not. You too have the ability to shoot fireballs after you’ve acquired the staff. The red wizard tends to guard certain items, while the white wizard avoids them. You’ve also brought a backpack with you this time so you can carry multiple items. Otherwise, it’s very similar to Adventure.

Release notes:

Here’s the latest version. I slowed down the “boss” in level 3 – he was kickin’ my ass too much. I also made his patrolling of the maze more random, as you could predict which direction he was going to come from. I also added a little logo to the title screen. This will probably be the final version of the game. The next step is putting it on a cartridge and trying it out on the real hardware – should be fun playing it with a joystick and not the keyboard!
