Amazing game! I don't know why I'm making a review only now (I played it on Steam last year). Sadly, I can't review it on Steam because I have a limited account so I'm reviewing it here.
I loved the character designs and CGs. Finishing it took me about ~6 hours (although I missed some stuff).
There were some parts that confused me such as when you had to get past the 3 train rails, so I had to look those up because I got frustrated lol. Also, I found it funny when (SPOILER vvv)
I accidentally flooded the elevator because I didn't realize there were other ways you could place the bulbs (?). I had to go back and realize that I was missing some.
I was also sad when I realized I missed some extra characters and Steam achievements, so I might replay the game in the future when Chapter 2 comes out or whenever I'm in the mood.
