This game's atmosphere was exceptional! Definitely one of my favourites of the jam :D
I loved the 2.5D artstyle, and the gameplay did exactly what I wanted it to.
I think I may have encountered a bug, or finished the game? I traveled to platform 5, then a train came, and I wound up back on the title screen.
Everything else, except for that, worked very well! The pysch-horror elements shined through, and I look forward to seeing if this goes further!
With these types of games, there's always the risk of explaining things too much, but I was a little confused when the shadows showed up - the psych horror elements came in a bit suddenly, and I wasn't sure what was happening. Once it clicked, I was able to immerse myself a lot more, but that transition felt a little abrupt to me.
The idea of the puzzles worked well, and I see in other comments that there may have been a bug with this in this build. That's all good, because the idea behind it works well so its an easy fix!
The idea of station rules / your own rules is also really interesting, but I think more fleshing out here would really make the idea of making your own rules to get through the world work well.
Overall, great effort and I look forward to seeing if anything more comes from this idea! :D
(PS - don't know if this comment is formatting weird for you, if so I apologise! I'm not sure what the issue is :') )
