Startup Idea: Task Management Tool for Game Developers

Startup idea to develop a task management software for game developers that allows separate and organized design of workflow, functions like a web of tasks, and features periodic updates and set timers.

I have been a game developer for some time now. I really need something to keep track of all the tasks that need to be completed.

However, I haven't found a piece of software that lets me separate and put together a proper design for my workflow.

It would be good to have one that works like a web of tasks and periodically updates and has set timers on it as well.
