Equinox

It continues Solstices isometric puzzle game style, with a greater emphasis on action adventure and the Mode 7 overworld map. Development of Equinox lasted from 1990 to 1993 and beyond the game's completion, due to difficulty running the graphics on all minor variations of SNES consoles. Brothers Ste and John Pickford were responsible for the programming, design, and visuals, and Solstice composer Tim Follin returned to work on the music with his brother Geoff. The game was released in November 1993 in Japan, in January 1994 in Australia, and in March in North America and Europe. It was critically acclaimed for its graphics, sound, atmosphere, gameplay, potential lifespan, and for the extremely high challenge level of its puzzles. The isometric perspective however, garnered a more mixed response. Some critics found it an intentional puzzle design aspect, and some dismissed it as a technical flaw, while others said the puzzles created from it were cheap.

Similar to its predecessor, Solstice (1990), Equinox is an isometric arcade adventure puzzle video game featuring elements of platform and RPG, such as using a menu screen to swap items and weapons. The game has a greater emphasis on action and adventure than its predecessor. The player acts as Glendaal, who traverses through eight dungeons to rescue his father Shadax from the imprisonment of Sonia, Shadax's apprentice. The dungeons traversed are Glendaal's home Galadonia, the forest kingdom south of Galadonia named Tori, a desert with ancient remains east of Galadonia named Deesa, the underwater Athena, the swampy Quagmire, a sea-surrounded kingdom with a large tomb named Afralona, the Ice Palace, and Sonia's resting place of Death Island. From smoke-puffing huts on the overworld, Glendaal enters the dungeons which contain an increasing number of rooms. The first has 16 rooms, the second 34, third 45, fourth 47, fifth 63, sixth 75, seventh 71, and the last 107. There are 458 rooms in total, much more than Solstice. Many of the rooms are barred by coloured doors that must be unlocked with matching keys, except red herring keys. Apples provide extra lives, and progress can be saved by simply exiting a dungeon. In a dungeon, Glendaal moves at right angles looking for tokens shaped as blue orbs. Twelve must be collected to summon a boss, all physical manifestations of the spirits guarding the bridges to other lands in the overworld. The bosses include a Bone Head that shoots ghosts; Dung Dung, a chunk of soil which pops out of the ground and shoots boulders; Pincha; Dollop, a blob of slime; Quetzalcoatl, a sentient pole-shaped statue made up of multiple blocks; Eyesis, a spinning pyramid; and Billy Bones, a ghost pirate captain who shoots cannonballs. Getting to the tokens requires navigating platforms, moving blocks, dodging spikes, killing enemies, and solving increasingly complex puzzles. The isometric perspective optical illusions form puzzles, based on determining the position of platforms. The rooms all have a single objective, and in some cases rooms must be completed in a specific order. Glendaal starts with nothing, but obtains tools to attack foes in his quest. Every dungeon contains one magical spell Glendaal can perform, including those for healing, freezing, slowing down and decreasing the energy of enemies, unlocking doors, destroying rooms, and viewing invisible blocks. The magic is powered by collecting potions, defeating vampire bats and trolls in the overworld, and the dungeon bosses. Glendaal collects weapons, including daggers, swords, axes, twin daggers, swords, scimitars, maces, and twin swords. A boss kill increases Glendaal's strength and provides him with one of five strings for a harp that can be played in the Overworld to teleport. In each room, all the foes must be eliminated to escape, and they can respawn upon reentry. Since Glendaal is killed in one hit, learning how to destroy all enemies in rooms is a puzzle. Enemies must be defeated to collect keys, potions, and tokens. Foes include ghosts, spinning devils that can only be harmed while stationary, bouncing blobs with random movement patterns, and plate-armored knights which are vulnerable on their back. Most follow a set pattern, but take several hits.

Released in 1990 for the 8-bit Nintendo Entertainment System, Solstice was the first original product of Manchester-based developer Software Creations, after conversions to 8-bit consoles. Programmer and company co-founder Mike Webb conceived Solstice, with the intention of being a Knight Lore-style isometric game for the NES. Published by CSG Imagesoft and in other regions by Nintendo, Solstice was released to a favourable critical reception and became a cult classic for its unique mixture of action, adventure, and RPG elements. Software Creations started the development of a sequel, Equinox in March 1990, four months before Solstices July release, and finished in mid-1993. As the first non-Japanese developer to have a Super Nintendo Entertainment System (SNES) development kit, Software Creations began by creating Equinoxs engine, which involved analysis of the Super Famicom. The project was produced by Ryoji Akagawa and Allan Becker, and executive produced by Sony's Shigeo Maruyama and Olaf Olafsson. Hiroshi Goto, Jeff Benjamin, Yuji Takahashi, Richard Robinson, and Software Creations founder Richard Kay were chief development executives, and Arthur Bangall was the chief game tester. Programming was initiated by Software Creations founder Mike Webb, and was mostly completed by Ste and John Pickford with contributions from Kevin Edwards and Stephen Ruddy. Whereas Solstice is a single-map puzzle game in which the player can only use magic, the Pickfords and Akagawa intended Equinox to be more of an action game by adding weapons, larger bosses, and RPG elements like discovery through multiple maps. In addition to Webb, Tim Follin, composer for Solstice, returned for Equinox to work on the music and sound, alongside his brother Geoff. The Pickfords were mainly responsible for the graphics, with additional visuals from Martin Holland and Neal Sutton. The visuals took more than one year to complete and unexpectedly prolonged development. Webb reported in April 1994 that Equinox was completed 18 months prior, but its release was delayed due to technical problems running on minor variations of SNES consoles. Blocks were made as sprites and overlapped to work within available processing power, but the picture processing unit (PPU) was unable to process sprites on the same layer properly, resulting in glitches like the foreground sprites disappearing. To fix the problem, rooms were redesigned, and sprites that disappeared were removed. Another major challenge was the isometric perspective, because 3D shadowing to indicate depth was impossible due to limited processing power. For animation and character design, Glendaal took the longest due to having many movements, and the bosses were done in a week. After the graphics were finished, the final part of development was altering the difficulty of Quagmire by removing a non-player character.
