Re: トレジャーアクション 脅され犯されモンスターの生贄にされたシェ}
If it's like the last "tower" game from them. It's one scene per enemies type + one for the boss at each milestone.
Haven't tried the game yet so can't say.
But yeah, the last one like this wasn't very fun. You just had to kill every enemies on each floor to get high lv enough to kill the boss with a couple of potion without buying them (drop power), and never die. had to die on purpose to get the scenes :/
Hope this time at least a "virgin" run gave you a full unlock
And yeah, the circle just do straightforward game that you run through in 20 mins - 1 h (depending on your japanese understanding and what you try to archieve).
If you're not interested in the text during the H scene, just rip the cg set really.
