I love the feeling and atmosphere in this game! The music is amazing! Almost a little too repetitive once I played for a bit, but still really good!
This is a fantastic game! Here is some hopefully helpful feedback!
Feedback:
-Needs some type of guide. I was confused and was trying to jump back in the mirror at the start thinking that's what I needed to do.
-platforming is hard. I assume you're using a circle collider? Sometimes I felt like I had extra forward momentum. Not sure if that is a code thing, or maybe some rotational momentum, just something to think about.
-in the light world, before the first elevator, it would be cool if there was a camera revealing the jump you needed to make. Same in the dark world over the pit.
-when I first encountered the sun (Thought it was a dog lol) I thought he was a boss trying to kill me. My gamer instincts kicked in when I heard the shooting sound effect, so some clarity in game would be awesome!
-when collecting the mini suns, I found one got stuck from the platform you jumped down from. an easy fix would be adding random velocity to the balls as they collide to avoid these loops.
-guide for when I completed all the tasks (lighting up the panels) I didn't know I needed to go back to the mirror
