3D Pinball: Pinball Power
- A simple but fun video pinball game with some early 3D-looking trickery, including the ability to adjust the camera-angle to your tastes. It used the two "C=" keys, situated on either end of the keyboard, to control the flippers in a way that felt similar to a real pinball machine, which was an immersive little idea at the time.Bubble Dizzy
- An arcade-style game in the Dizzy franchise, where you have to climb up from the ocean floor using bubbles of different speeds and sizes before your oxygen runs out. This was available on several systems and was a mini-game in The Fantastic Adventures of Dizzy for the NES, but I've always been fond of this particular version and its bubbly/fizzy-sounding music.The Caverns of Eriban
- Interesting side-viewed space-flight game where you have to pick up and deliver supplies within a large maze-like cavern, whilst trying not to crash. Features a distinctive chiptune version of Mercury, the Winged Messenger from Holst's The Planets suite as its theme.Guns 'n' Ghosts
- A Halloweenish modern homebrew title in the vein of single-screen arcade-games such as Bubble Bobble. Has two characters with different abilities (one who uses guns, one who uses psychic zaps), plus a simultaneous two-player mode.Nebulus
- A platformer whose stages are rotating towers that must be climbed. Also ported to other systems under the names Castelian, Kyorochan Land (it was reskinned into a candy-licensed game for the Japanese release), and Tower Toppler.Park Patrol
- An unusual game about a park ranger keeping the park clean and its guests safe. It has ridiculously catchy music. Props to you if you can master the log-rolling mechanic - it's quite tricky!Platman Worlds
- A modern homebrew platformer featuring a Pac-Man-lookalike character in a side-viewed flick-screen world. Tougher than it looks!Santa's Xmas Caper
- Not the greatest shooter ever, but a festive novelty, since you don't see too many Christmas-themed "cute 'em ups" out there. Not to be confused with the versions for other computers - they're all different games that were released with the same title and box-art.Scooby-Doo & Scrappy-Doo
- A short-but-sweet four-level NES-style platformer (something that was becoming in-demand at the time as the cartridge-based consoles and their platforming mascots began to take root in the UK) starring Scrappy-Doo, which can get quite tough towards the end. Not to be confused with the earlier Scooby-Doo game, which is awful. Also not to be confused with the Atari ST/Amiga version of Scooby-Doo & Scrappy-Doo, which is a completely different game.Yogi's Great Escape
- Another one of those sort-of-NES-like platform games, this time using the Yogi Bear license. Not to be confused with the numerous other Yogi Bear games on the system.
I also second the suggestions for Creatures, Impossible Mission, Jack the Nipper II: Coconut Capers, Little Computer People (make sure that you use the disk version and not the tape version, though - the tape version is missing a number of features and only offers a plain nameless Little Computer Person for you to interact with, whereas the disk version came in many variants with different names and looks for the person), Mayhem in Monsterland, Samurai Warrior: The Battles of Usagi Yojimbo (which is even better if you're already familiar with Miyamoto Usagi from his own comics or his cameo appearances in the Teenage Mutant Ninja Turtles franchise), and Zamzara (and its phenomenal music!).
