Originally my opinion on OneShot was that it was a unique and interesting concept, with characters and a world I was interested in. In terms of gameplay though, it left a lot to be desired. The gameplay was incredibly basic and not very engaging, and while the gimmick of solving puzzles by looking outside the game itself made the game unique, the game really didn't do enough with that, along with the ending feeling half-baked in my opinion.

And then I played the Solstice run.

This is where the game really shines. All of my complaints are pretty much nullified here. The game still revolves around puzzles and interacting with objects in the environment, but story wise and in terms of how it goes about the previously mentioned gimmick, it's a whole lot more engaging. I was very much immersed in what was happening. All of the characters are memorable and the way you interact with the world is incredible. The Solstice run of OneShot makes the game for me, it's a fantastic experience, up there with some of my favorite games I've ever played.

It's just really unfortunate that the experience of OneShot as a whole is having to get through that initial run that isn't that great, waiting for the game to get good once Solstice comes around. Not to say that the first run of the game is bad, but it's not anything amazing, it's just alright, which is a little frustrating.
I still highly recommend the game but it isn't without its faults, that's all.
