Very annoying control scheme that is clunky and, in short, anathema to fun. This applies to all aspects of gameplay, too. Movement and escaping are nightmarish endeavors that seemed to have never been pplaytested. The invisible wall is buggy as all sin and actually crashed my game multiple times due to endlessly looping the text for needing to turn around. Vore creatures are absolutely lovely, but lack of any stages in animation makes for a game that's largely a tease. No digestion, no stilling of your character, no further dialogue. 

Time constraints make some things far more understandable, such as lacking bonus animations and dialogue, but the wretched controls are a rather egregious oversight.
