ITL co-developed and ported several classic titles for Taito and other publishers, including the shoot 'em ups Abadox, Halley Wars, and Arrow Flash. They also worked on the action-platformer Don Doko Don, which is closely associated with Taito's Bubble Bobble franchise, and the sci-fi action game Cyber Cross.
During the late 1980s and early 1990s, the developer shaped the gameplay landscape of major arcade franchises through precise console translations and original designs. In
Volfied (1989), also released as
Volfiev, the studio revitalized Taito's classic territory-claiming mechanics, introducing futuristic art assets, barrier systems, and individual level bosses that redefined the genre.
The studio's work on
Don Doko Don (1990) directly expanded the cooperative, single-screen action design popularized by the
Bubble Bobble series. By utilizing similar mechanics where players stun and throw enemies to clear stages, this title cemented the developer's role in refining Taito's signature platforming formula for home consoles like the PC Engine.
Additionally, the company delivered technically demanding projects such as
Kagerou Densetsu (1990) for the Family Computer, a sci-fi role-playing game that showcased their versatility beyond arcade ports. Through these releases, the developer bridged the gap between arcade hardware and home systems, ensuring that key design philosophies from major franchises successfully transitioned to the Nintendo Entertainment System, Sega Genesis, and PC Engine platforms.
