It's always a euphoric experience when you play a visual novel for the first time, & you go into it with the most positive attitude... & yet you finish it off with a broken heart in many ways, yet you wouldn't trade that pain for anything else in the world. THAT was what playing Echo was like for me.
I remember vaguely coming across a comment years ago saying that something along the lines of, "You're probably not mentally ready for what this vn will do to you." I took it with a grain of salt & hit download. The more routes I played, the more my heart shattered, & the more invested I found myself wanting answers. Like... the end of Tj's route man. That broke me.
All in all, if you're thinking about giving this game a try, do be warned: it's not for the weak at ALL. I shed some tears, & my overall perspective has changed from first playing the game. I'm definitely not the same from when I started, versus finishing as of last night. A beautifully written game, I recommend playing it at night, since that's what I did to heighten the experience for me bwahaha, & grab yourself a drink. Preferably alcohol for my tastes, but juice or water would suffice just fine.
Kick back, TRY to relax, & enjoy the wondrous story Echo has in store for you :)
