(Minor Spoilers)
I thought it was pretty cool so far. I'm not the biggest fan of these horror games, but I decided to give it a shot out of curiosity and was somewhat pleased. A diverse cast of characters and the idea of a killing game on a train felt like fresh air. Ikuro was hella annoying with his dickhead attitude, I won't lie, but I found myself liking him more than the rest of the cast for some odd reason. That ain't a criticism; I'm just weird like that. I couldn't begin to explain myself.
If I had a few criticisms, it would be the navigation. Though it was a little easy for me to find doors after some trial and error, I imagine some of them are having trouble. The investigation part stumped me, and I'm not proud of how long it took me to solve the problem.
There's also something with the writing that bothers me personally. I think it could use some editing because I skipped much of it. I felt like I wasn't going anywhere. It was like I was reading just to read and not learning about the world or the people around me. What's worse, once I was done skipping, it didn't feel like I missed out on much. It ain't the worst thing in the world; it just could use some editing.
Despite its faults, I hope to play more of this game of yours! To no one's surprise, it's the execution portions that got me going. I look forward to the events leading up to the games and the games themselves. What would make it cool is if you did different variations of this little trolley problem of yours (Which you're likely doing regardless, but I'll say it anyway.) No, I don't mean wildly changing the premise of the game, but the trolley problem did have variations, and I doubt it would be any fun letting the watch do all the work. IDK, I'm not you guys; I'm just spitballing here.
Overall, cool game. I thought the things on the back of their neck would explode on some Suicide Squad shit, but what you got works, too. Keep it up!
