### Re: Elementum for Electron and BBC Micro/Master

Brilliant and original game.

My only suggestion is to make additional keys, such as A and S keys, move the electron left and right as well as the Z and X keys. This way, the game can be played under emulation on PCs with foreign keyboards such as the German QWERTZ keyboard.

The Rocketman sprite in the first Planet Nubium game was drawn using the XOR method. Here the background undergoes a bitwise XOR with the sprite. The method is quite simple and the same bitwise XOR routine is used to remove the sprite. However, with this method when Rocketman crosses over a coloured...

Planet Nubium Two uses a sprite mask to display the Rocketman sprite. First, the background where the sprite is to be plotted is copied to a scratch area of memory. The screen memory then undergoes a bitwise AND with the sprite mask, then undergoes a bitwise OR with the sprite itself. The result is ...
