You know that most developers aren’t creating their games from scratch, right? They use game engines. It sounds like your machine has an incompatibility with the game engine, which is hardly a fault of the game.
It’s like you’re saying a book sucks because you got a papercut when you went to open it.
The dev even notes in the description that the browser based game isn’t reliable (it’s probably pretty difficult for any engine to work with every browser on every operating system of every device that can access the internet)
