UP2037603: I was very impressed by the quality of 3d models as well as their working animations (both the looping animations of the enemies and barrel roll/dodge of the player). I did find that it felt as though the barrel roll and dodge didn't seem to help the player as ignoring the enemies seemed to do no harm (although perhaps simply should've been done for longer). The sound effects were well suited to all that they did within the game and none felt out of place or overly loud/quiet.
Although the shooting mechanic feels somewhat optional, the reticle that follows the player's mouse is a minor feature that, in tandem with the tracers of the projectiles towards enemies, greatly aids the atmosphere of the game.
