- Menu music sets a good tone. Overall very pleasant to look at
 - Missing music in game. Needn't be as loud or prominent as in the menu, but just having anything would be nice
 - Jumped against first book, threw my weapon, flickering model indicates invulnerability frames to me. In the same jump arc, touch second book while still flickering, resulting in death. I-frames could really last longer than a single second
 - Jump feels sluggish
 - Need for ammo limitation not entirely clear
