Tested with multiple versions of Proton; only 3.7-8 Beta actually runs past the intro/logo clips. Gameplay seems fine, until reaching the first scripted animation sequence, involving the first character seen face-to-face in the game (guessing Yeesha). At this point, while the character is rendered and the camera pans around as though following a moving target and the music rises and falls seemingly to fit words being spoken at each corresponding point in the script, the character itself doesn't actually move and the voiceover doesn't play. Additionally, the controls are disabled at the start of this sequence, and never reactivate after. Thus, the game is unplayable at this point.
