In short - my main gripes with the game are the clunkiness, the grindiness, and the lack of things to do.
There's a few aspects to me calling the game "Clunky". The main walk speed is painfully slow. The sprint speed is significantly faster, yet still somehow feels sluggish. In fact, almost everything about the game feels sluggish - in some areas understandably, so, but not always. Collision boxes can be quite large and make it awkward to walk near objects/walls/people. It can also be awkward getting around to the right side of the damsel, as there's a different option for front and back ties. There's also the usual "faster than my walk speed, slower than my sprint speed" thing that NPC's do when leashed (when they do actually follow you, anyway - a few times when I first started playing, the leash would attach but they wouldn't follow). It's just not too smooth to play, nor is it the thematic clunk of, say, awkward controls in horror game.
(Oh, and also - you can't choose the map. Random selection as to whether you get the village or castle map. Would call it clunky too but not control-clunky?)
With regards to grinding... well, it's grindy. Upgrades vary from 5k to 15k, clothing types and accessories from about 1.5k-5k, individual colours a few hundred, but depending on the specific game mode and your performance, you only seek to earn about 1.5k every 20 minutes. And the upgrades aren't exactly extensive, either - some stealth buffs and drop increases but not much. And the clothing types aren't too extensive either - one dress, one set of pants, one long-sleeve top, options for a hood, satchel, longer boots, but no differing styles, and the "underwear" are the ugly Skyrim-style cloth wraps for boobs and plain panties. There's no preview before you buy either, so you have to rely on seeing the clothing out in the wild if you want that. I think the game just uses the one character model with different customisation options, anyway.
As for the lack of things to do - well, there just isn't much to do, frankly. People are complaining about the "no sexual content" tag and, while I do agree not every adult game needs sex, you don't really do anything once someone's captured. Or you're captured. There's a (very brief, static) "game over" scene in one mode where losing is an instant loss, but getting captured yourself in others is just a time impediment while your character quietly struggles for a bit. You can tie up girls in a progression (wrists, elbows, feet then hogtie) and... that's it. Tying from the front seems to only allow a front wrist tie. Occasionally they might moan and you can gag them. There's also a roof mounting point where I think you can do more extensive ties, but that kept bugging out for me. Characters don't actually tie others up, either - the character getting tied just moves a bit and the ropes appear on them, while the other stands there, not even doing a stock animation.
Overall, it's just... well I wouldn't say the game is outright bad, just lacking. I do give a bit of leeway to smaller studios doing these sorts of big-engine games, but the gameplay's just not fun and there's not actually that much content. If there was a bit more engagement with regards to catching people and getting caught, there could be a fun game here, but as it is, it's just a kink game that doesn't demonstrate the kink all that well.
