Thanks for replying.
I hope I did not come across as too negative, but if I listed al the things I liked then my feedback would have been too long.
Regarding variety, maybe you could let the story help inspire you? Whoever captured Eliza seem to want something from her, and the dungeon/facility Eliza is in is a big mystery, so there are a lot of unknowns to elaborate on. The same goes for the world in which the game takes place in. I do not know how much or little it deviates from our own. So, there is a lot of creative freedom for you to make up stuff, like making bondage themed things and events a more normal part of the world, that could fit the setting for whatever direction you want to steer the game towards.
For instance: Do the captives have other tasks for Eliza? Maybe Eliza has to capture other captives, who have gone out of control or is trying to flee. There could be challenges which Eliza had to complete with certain restrains, like jumping over wires with her ankles tied together (I would not mind more bindings however), and that could be implemented into a minigame. Maybe they want certain “other services” they want her to perform. How clean or dirty you want to be with this game is up to you of course. I personally prefer the more light-hearted approach to bondage in games, like DID-napper do, but I am not the developer.
An important thing for me, when I play games that align with my kink (bondage), is when the game “rewards” the player with bondage content, like pictures, scenes etc., for playing well, for making progress in the game. Right now, we only get the bondage part of the game by messing up, whether intentionally or by mistake, and if we do well, we get little to none. I find it much more rewarding to play these sorts of games, when I know that by completing the challenges and making progress, more options will open up (also more kinky options), compared to bondage-themed games, were the only way to get to bondage content, is by messing up and going for game over, or going for a game over like status.
The player does get something after a run, like outfits and restraining gear obtained, but I think it needs more. The “save area” have 4 rooms, and more could be implemented, so they could be used for more after each run. Maybe a place where you can get quests, exchange excess loot, and maybe get upgrades or a room for playing around, maybe the woman you can talk to, could get into the fun, after enough successful runs. I would like for scripted events, like a cutscene, to appear while you make progress in the game.
I do not know how much time and effort you want to spend on the story part of the game, but I do like the humorous dialog and commentary you have provide so far, and I would like to see more of that. And it might help inspire new gameplay, and give ideas to what to do with the game in the future.
