Sometimes the train will leave and Val will disappear, but the scene doesn't change. I've been able to press ESC to get Val to reappear, and choosing a different train door to go into seems to work.

I can't jump while simultaneously moving right. I can jump while simultaneously moving left. I also can't hold down the right key and wall jump at the same time. The left key doesn't have this issue.

Rob's shop won't do anything. Talking and leaving works fine, I just can't open the shop.

I'm using the web player running ver 0.18.14b. Idk if these issues will stay if I downloaded the game, but I don't want to lose my progress. (Just finished visiting the whole city)

Other than these issues, I have fallen in love with this game (big fan of good pixel art and sweet pixel animations and lore)

Also, adding a mission tab to the menu would be great so that I can remember my current mission.

Also, just broke the game. I surfed on the body of water under the train station at the weather station and I fell right through it and now I've fallen out of screen and can't get back.

I also got the same problem, that val disappears when I try to do to one station (third station from the end of the line, the one after the land where you obtain orca kick). 
Also, there is a problem with that orca kick, because I can't perform it anywhere else than in the place I have obtained it.

Yes, I play the web version. Yes, I love the game and think it's very well made. Yes, I enjoy the art.
