Version - Prototype 0.0.3 (Preview)

The level 1's second half is now added. You can keep playing after finishing all the puzzles on the train and arriving at the station.

I'm still adding necessary content,  refining the game flow,  and fixing bugs. I expect to post the full version of 0.0.3 in 1-2 weeks.

Thank you for your interest and attention to this game!
