This game is surprisingly deep for a web game! Love the tough choices, makes you really think. My only wish is that there were more branching narratives, but still a solid experience for a bus ride.

This game is surprisingly deep for a web game! Love the tough choices, makes you really think. My only wish is that there were more branching narratives, but still a solid experience for a bus ride.
One Chance is a brutal game if you're trying to 'win' by saving everyone. It's all about making the optimal choices, and the replayability trying different paths is awesome. Wish there was a clear score metric though!
As an adventure game veteran, One Chance stands out for its unique premise and high stakes. The 'one shot' mechanic is brilliant, even if it's kinda heartbreaking sometimes. A solid entry, but I'm always hoping for more content updates!
OMG this game is so intense! I've never played anything like it. Every decision feels massive and I cried at one of the endings, lol. It's seriously captivating and I highly recommend it!
The design of One Chance is fascinating. It's a masterclass in player choice and consequence, forcing difficult ethical dilemmas. The limited playtime really ups the ante. My only minor critique is that some paths feel a bit too linear, but overall, it's incredibly well-executed.
