1K Intro Demo 'Wall-run' for ZX81 (2015)

Wall-run is a simple open-source machine code game developed by A. Millett in 2015. Designed for the ZX80 and ZX81 platforms, it offers a unique gameplay experience focused on strategic movements and quick reflexes. The game is available in both 1k and 2k+ versions, providing different features for each.

In Wall-run, players use the 'WADX' keys to control their wall, aiming to trap the computer opponent. Successfully trapping the opponent allows progression to the next level, with increasing difficulty as the levels advance. The game challenges players to trap the computer multiple times depending on the level number.

The game also includes a scoring system where players can collect bonuses in the form of '$' symbols. These bonuses contribute to the overall score and are worth more points on higher levels. The 2k+ version enhances the experience with a larger screen, score/high score tracking, and a title screen.

Overall, Wall-run is a compact yet engaging game that showcases the capabilities of the ZX80 and ZX81 systems. Its open-source nature allows for exploration and modification, making it a notable entry in the demoscene and intro categories.
