This was my first Android game, and it's still under development. I recently made all 6 episodes available in the free version, albeit with some hopefully unobtrusive ads. Here's the promo text from the Play store: "Eight Bit Jim is on an adventure. His Pixel Jump-jet has run out of fuel and he needs to find some on a desert island. But it's not that simple. He must run around on PLATFORMS, jump over BADDIES and collect COINS, which is how his days usually turn out. It's almost like the last 30 years didn't happen. This game doesn't benefit from recent advances in graphics, sound effects and AI. As far as Eight Bit Jim is concerned, it's still 1983." The idea is to create a game that reminds players of early 1980s computer games, and is fast and fun to play. My target audience is people in their 30s and 40s who remember games on platforms like the ZX Spectrum (in the UK), or the Commodore 64 and Atari 2600.
Several of the levels are themed to look like the ZX Spectrum (another UK classic, which might not be so well known in other countries). I have it on my to-do list to try to emulate the "colour clash" that used to result when graphics of differing colours moved too close to each other.
