But they wanted a lot more than that. Engines like Phaser work hard to take care of browser quirks for things like PointerEvents vs. TouchEvents vs. MouseEvents or supporting mobile devices. Sure, it seems simple at first until you run into those kinds of problems and reinvent the wheel... learning an engine isn't terribly complicated but I understand the sentiment for a one-time project. It just seems like they did so much other planning but didn't want to plan the UI implementation to the same degree?
