POTENTIAL SPOILERS BELOW:
A brief but enjoyable visual novel that, in some ways, felt like something of a throwback (in a good way!). In particular, the CG of Caitlyn and James in the observation room and then of Elliot's perception of them felt retro but nostalgic, which may have made the short playtime that much more palatable. Though we didn't get to spend much time with any of the characters due to the game's brevity, I thought that they were well-established in a short amount of time: In particular, Caitlyn's almost desperate wish to help Elliot and the mention of going through multiple actors because they couldn't stand deceiving Elliot for long seem ripe for elaboration.
The hook, of course, is the perspective-flip, which works very well; Elliot's perspective, in particular, illustrates the odd foreshadowing during the 'hanging out' scene, and seeing Caitlyn and James interact as actual people makes Elliot's perceptions of them hit harder. The VN feels more like a prologue than something self-contained: Elliot may be suffering from a debilitating but mundane condition, but the details of his treatment seem to indicate otherwise. This is a lot of set-up for one person, especially considering the mysterious "They" and James' interest in Elliot's perceptions. I supposed Elliot could just be related to someone wealthy or powerful enough to dedicate these resources to him, but it feels like there's a larger story here; if that's the case, I hope to be able to play that game, too!
