Thank you for playing! As a fellow motion sickness person, I felt like FOV is a must in terms of accessibility when it comes to 3D first-person games. We are super happy to see our efforts get noticed :)
The white icons are actually bonus collectables that could be found around each level. These being the indieformer gem 
, the jamlystics jam 
, and a gold bar 
. All of these were meant to improve replayability and encourage players to explore the map a bit more. Should have conveyed that more clearly, but sadly got left in the to-do piles.
