GB Monster Maze

"Roll up, roll up, see the amazing Tyrannosaurus Rex, King of the Dinosaurs, in his lair. Perfectly preserved in silicon since ancient times, he is brought to you for your entertainment and exhilaration. If you dare to enter his lair, you do so at your own risk."

Based on the 1982 Sinclair ZX81 classic, "3D Monster Maze", conceptualised by J.K. Greye and programmed by Malcolm Evans, GB Monster Maze is an interpretation of what I believe the game would look like, had it been adapted and released for the Nintendo Game Boy.

There are two gameplay modes: Modern and Classic, the latter of which is essentially a direct port of the original. The former, however, has been achieved through basic raycasting, the same method used to create games such as Wolfenstein 3D.

Controls:

The controls have been translated from the Game Boy as shown below, and do as expected. A basic rundown of the in-game controls can be found on the main menu, although they are fairly self explanatory.

If the default colour palette is unpleasant for you, there are alternate palettes that can be accessed by using the arrow keys on the startup screen, à la Game Boy.
