Glitched Into the Ominiverse

What if the game you were building… became your only lifeline in another universe? Luke Haken was just a regular game developer—overworked, sarcastic, and more comfortable debugging code than dealing with real life. But when a reality-shattering event pulls him out of his world and dumps him into the Marvel Cinematic Universe, survival becomes more than just guesswork. Waking up homeless in New York City, with no identity, no allies, and no clue how he got there, Luke discovers something impossible: a system—his own unfinished game app—has embedded itself in his mind, complete with a class selection screen, skill tree, and stat-based progression. It’s not a dream. It’s not a simulation. And the stakes are terrifyingly real. To survive, Luke must grow stronger, faster than the world around him can collapse. As the system begins unlocking new worlds beyond the MCU, he realizes this is only the beginning. The journey across the Ominiverse has begun. — Description from novelcodex.org
