Rating v0.6.4a (edit: I did finish all available content):
Summary: 55/100. Exhausted plot tweaked again to publish more porn art of breast-implant Lara Croft taking on magically-sized dongs. Storytelling could use a good editor.
Story: 50. Given the fairly developed world of Lara Croft, the writing does little to explain exactly when this story takes place in the timeline of the existing publications. Some references are made to a character here, or a place there, but the most solid method of determining when this particular story takes place is by determining the size of Lara's chest (see below for more critique on that). As for the plot itself, a possessed talisman wielding the power to corrupt any individual touching it isn't exactly a new concept, but I suppose such an idea is fitting in a world of dungeon raiders and tomb delvers.
Originality: 20. Lara doesn't currently reside at her ancestral mansion; there's a change from the original story line. That's all I've got, though. Using a sentient artifact of corruption is a common theme in adult games, and even the characters are trope-heavy and lack unique qualities.
Characters: 60. Lara herself doesn't seem to hold much individuality in this title. Other characters include: a strict librarian with a BDSM fetish; an evil deity seemingly locked within an ancient handheld object (but not a genie!); a 2,000+-year-old boy toy who, given his age, seems to lack personality and is too obviously only there for plot porn purposes; and a fellow one-percenter who possesses more knowledge on Lara's mission than she does herself and will use that knowledge as a weapon against her.
Renders: 75. Mostly well done, though facial expressions are distractingly off at times. And, as mentioned earlier, Lara's breast size (and most of the penises) are ridiculously proportioned, detracting from my immersion and appreciation of the H-scenes.
Sound: 70. Music plays throughout and sound effects (mostly non-communicative vocal sounds like heavy breathing, grunting, and moaning) add some flavor to many scenes.
Gameplay: 30. Completely choice-based, but not completely binary; although some "choices" merely determine the sequence the available options play out, none of which affects any follow-on story elements, rendering the sequencing options moot to begin with.
Performance: 100. No observed issues performing on my 6-year-old laptop.
Bugs: 100. No observed glitches or app-crashing issues.
Animations: 40. During H-scenes, an attempt was made; short, GIF-style animations run for a second or so before reversing on themselves back to their original position and replaying on loop. Otherwise, some transitions show minimal animation such as one-time eye or hand movement.
Voice Acting: 10. Does heavy breathing count? Dialogue throughout is not voiced, but vocal sound effects here and there contribute to some scenes.
Grammar: 40. Passable English storytelling, but many phrases and sentences could be tweaked for better flow. Highly recommend recruiting a capable editor.
Amount of content: 64. Arbitrary amount solely based on the version reviewed.
