What can I do? I can't trigger any h-scene, not even If I play at the lowest resolution and stay still for half an hour while being hit by monsters. Nothing ever happen. I can't even collect coins.
Problem Statement: Could not trigger H-Animation during battle
Troubleshooting : Are your games lagging a lot?
Possible solution : Do not run Cheat Engine on the background (or even any additional apps) and try running the game again.
Troubleshooting : Your game runs smoothly but still could not trigger H-animation
Possible solution : I don't think the game came with 'H-Scene On/Off button'. If you can run the game, then it should not be anything regarding files issue, or maybe the game folder you get was altered by a third person before sharing? I don't know man, probably not the case though.
So I could only assume that you were punched too far by the enemy that makes you auto-stand-up before they could approach you while you lay down (or the enemy took pity on you and turn away blushing). I'm not sure if unequipping will disabled the animation, so probably nothing regarding equipment-wise.
... One way I could recommend is to test it on Easy, cut down the number of enemies to the last one or two, then approach them while they are further away form your Crystal Tower, and stand near a wall or boxes behind you, one of them will probably trigger 'Capture' after punching your guts.
Troubleshooting : Do you have keyboard/gamepad problems?
Possible solution : Probably need to detached gamepads? Maybe?
Troubleshooting : You can not view H-scene in recollection
Possible solution : ...
Sorry mate, if I could not help you.
Anyway, for anyone new,
1. you can go to full screen by pressing [F11] while in-game (after the RPG MV logo).
2. Once you get scrolls inside your backback, like from chests, use the item first from inside your backback, then, while in battle-stage, you can deploy the scrolls item by summoning traps (it consume MP).
3. You can also use [Heal] once you purchase a [Ring] from the item shop on the North East. Skill like [Heal] can only be activated once you start a [Wave] during battle-stage, by long-pressing the white bubble on the middle left screen (by the current default, it consumes 40-MP, so look for a 40-MP white-blue bubble).
4. The first battle stage (1.1) is due North, after that, on the same gate-floor, exit East twice is the second stage (1.2), exit North-East from there goes to third stage (1.3). Then, you need to talk with people/get an item before proceeding to North-West North-West from Save-Orb to go to the next stage (2.1), and so on. Stage 1.3 is my personal favourite as the floor design is easily the best to gain superior advantage with traps.
5. Each stage is replayable, but leveling in this game is close to useless if you ask me.
