Ah, but you, the reader, are not Chase, and that's the point the VN is trying to make (Jenna's route will make this clear, that's all I can say without spoiling it for you). This is one of the reasons why I love Echo, it plays around with genre conventions and standards, making you question everything after a plot twist is revealed. It is no coincidence that "real" choices are very limited in Echo, compared to most other VNs.
And with Flynn, pay attention to the moment the perspective changes. What happened to Chase that caused the change? Why did we follow Flynn and not someone else? It all has a purpose and ties together, and coming up with theories and trying to find the real reason is 60% of the fun I got from playing Echo.
Also, notice how in Adastra you can chose Marco's name, but in Echo Chase's name is chosen for you.
PS. Echo isn't a thriller VN, I'd classify it as horror/mystery. So you'll be disappointed expecting to get a thrill out of Echo without putting any work in yourself.
