I really appreciate you giving this game a try and completing it. It's nice to hear that the art is good because that was one of my main priorities this jam.
Basically, the main consequence is the death counter. The wheel of mind that you run into in the soul realm will scale based on number of deaths, and it becomes harder to reselect your active mode. So, if I'm in light mode with 10-15 deaths, the chances of getting light mode again are very slim and vice versa. I did not explain mechanics like this at all, so it seems like random rates are applied in places. I also completed the level design for body realm in 10-15 minutes of the last hour, so I was really in a crunch. I didn't get to explain any of the mechanics, and it seems most confused many. I always say I want to leave 1-2 days for playtesting and polish, but I never do. I'll be taking a new approach next jam and see to it that clarity is a priority. Thank you for the feedback.
