A really good game jam submission. I liked the game concept with the door between light and dark. I think there is still a lot potential to add more mechanics to this. I like the game art and music too.
Here are some 'problems' or 'bugs' I had while playing the game:
- It seemed like some parts of the game window were cut off / in the menu you could not read the whole game name and sometimes it weren't possible to see where the next platforms are (light or dark 'mode').
- The character did not move with moving platforms - felt a little bit off
- I did not die after falling down I still could walk but could not see my character
Maybe you have to change the camera size/behaviour a little bit.
Apart from that a really good game jam submission. Was fun to play.
Greetings
