McNally's first published video game was a side-scrolling helicopter shooter titled Tiger's Bane, programmed on the Amiga. Previously known as a demo by the name Flying Tigers, the game went live on November 11, 1997, published through Aminet. The same year, Seumas formed the software development company Longbow Digital Arts (also known as Longbow Games), working together with his father, Jim McNally (game designer), his mother, Wendy McNally (lead artist) and his brother, Philippe McNally (3D artist). The company released DX-Ball 2 in 1998, a sequel to the 1996 cult-classic PC game DX-Ball by Michael P. Welch, while simultaneously working on the 3D terrain tank-racing game Tread Marks, which was released in 2000. While DX-Ball 2 had accumulated more than 5 million downloads by the end of 2002, Tread Marks won three Independent Games Festival Awards for "Best Game", "Best Design" and "Best Programming". Other products McNally programmed include Particle Fire, a screensaver exhibiting a fiery display of flexuously moving particles; Texturizer, for creating seamless textures; and WebProcessor, for creating fast HTML macros.

McNally is credited for visual contribution to the original DX-Ball by Michael P. Welch (creator of Pocket Tanks), a freeware computer game for the PC first released in 1996. The game, originally based on an earlier series of Amiga games known as MegaBall, is patterned after classic ball-and-paddle arcade games such as Breakout and Arkanoid. DX-Ball has been succeeded by four follow-ups: DX-Ball 2 (1998), Rival Ball (2001), Super DX-Ball (2004) and DX-Ball 2: 20th Anniversary Edition (2018).

Developed by Longbow Digital Arts as a derivation of the original DX-Ball, DX-Ball 2 introduced the feature of board-set selection, allowing the player to pick between various sets of boards to play. The free demo came packed with a total of 24 boards divided into 6 board-sets of 4 boards each. Additional board packs could then be purchased and installed for more boards, whereas the initial Board Pack 1 expansion would extend the demo board-sets into full sets of 25 boards each, summing a total of 150 boards. While a total of five board packs were released for the game, DX-Ball 2 was later succeeded by Rival Ball in 2001.

McNally was diagnosed in 1997 with Hodgkin's lymphoma, a type of blood cancer, at the age of 18. McNally died on March 21, 2000, shortly after winning the grand prize for Tread Marks.
