I stumbled upon this game a while back on the Google play store. It had a free demo which I loved so much. Sadly, because I was a kid, I couldn't buy the full version. Years later, the name suddenly popped in my head, and Iooked the game up again and found it had a steam version! I bought the game and it was worth every cent. Awesome soundtrack. Slowburn story. Great dynamics. And lovable cast. To keep this review fair I also need to list my complaints. The game got a little repetitive with finding the items required to fix the rocket. The game was also extremely short, and left me wanting way more than what I had. The epilogue was great but needs to be downloaded seperately, which was a hasstle. Other than that it was a 10/10 experience that got me to buy the entire Opus series. If you like slice of life media, visual novels, great scenery, and awesome soundtracks you should buy this game.

I first played through [i]Rocket of Whispers[/i] in 2018 – back then I thought it was a beautiful story and concept wrapped with some clunky mechanics. I liked it a lot, but being a short 4-5 hour experience I expected to forget about it soon enough. It turns out the story stayed with me much longer and more strongly than I expected – My grandmother passed away about 18 months after I played, and this is the first piece of media that came to mind as I looked to put my feelings in order. ‘Rocket of Whispers’ is named aptly- it’s a quiet game, based around the premise of two people, possibly the last on their world, attempting to perform a final ritualistic ‘space burial’. This involves launching a rocket to reach the fringe of space, a ceremony designed to bring peace to those who have died. The story both past and present unfolds as one of the player-protagonists, John, scavenges the landscape around the rocket factory for the materials needed to complete the mission. It can be a frustrating process, John is impeded by the environment, sometimes unclear direction, and the often-irritated voices of the ‘spirits’ of the departed who demand that he do better. In my first playthroug…
