Original concepts, though I needed to read the help information to get anywhere.
There is nothing intuitive about the game. The user interface is deserves special mention - it is unlabelled (and colour choice makes them sometimes hard to read) for example, and its not clear which bars/meters the player should aim to score. The resulting tip provided on failure can be entirely irrelevant or redundant (if the player demonstrates an understanding of how to use the scissors feature, why would you display them afterwards?)
The shop/inventory system isn't so useful, because with an understanding of the game mechanics the item effects are redundant (the item effects are of too short duration); but without that understanding the items are of no help, neither as a substitute to understanding each girl's "sequence", nor as a learning aid.
Additionally the hint/s personal information is plain misleading, and the actual hitboxes of some cursor designs are hard to judge and make stimulating say a nipple or clitoris needlessly difficult - looking in 3 places at once (to read the part name identifier, to see where the cursor is, and to keep an eye on the "wakes up/fail!" bar) is a pain because of the design.
Additionally, the choice of using CG rendered girls on the title screen is jarring when the in-game are 2D styled.
Worth a play - but not worth learning through trial and error alone. Know when to quite and visit the help files.
