The artistic direction is great and switching the characters with different strength and weaknesses was really cool, reminded me of the game 'Obscure'. I enjoyed how the dynamic and story between the characters played out. I don't want to spoil anything, but the story started to unfold layer after layer and the gym scene definitely gripped me.
The biggest flaw of the game would probably be the controls. The camera being sluggish doesn't add to the experience and I guess you used some kind of circle collider or distance measure for interaction? I think giving the player precise control is crucial, because the main game mechanic is finding stuff. Some kind of raycast or cylinder collider aligned with the camera view would fix the issue.
Some small caveat: I really liked the dialogue box. Easy to interact, animated words and there were even subtle timing adjustment during the typing when a dot was typed which improved reading quite a bit.
Great work you all =)
