Well...
This was an mostly just ok combo of VN and game. I dunno how other people found this thing, but for me, it was pretty easy to beat the game. Didn't need multiple tries or anything. I just paid attention to the flavor text on each heroine, took into account how the traps work, along with the map layout and then beat their asses. The hardest was actually the first heroine, because I didn't fully understand how the combos worked and how movement worked and all that, but I still clapped her ass in the second map without any real difficulty.
The only genuinely hard part of this thing actually involves getting the special scenes. There's two for each heroine, and each scene is related to beating the heroine with the special monster located in the 2nd or 3rd map. Achieving that can actually be difficult... and it's absolutely annoying since there's a measure of RNG as well with some of the heroines which can make containing them to establish trap chains difficult. This is especially noticeable with Hilda.
Personally, I didn't bother, since it means replaying each "fight" several times and the game simply isn't interesting enough for me to do that. I recommend just beating it once overall, then grabbing the full save on the 1st page.
This is because the game doesn't have much in the way of story either, which means that it's simply not interesting on its own to replay repeatedly. The extra capture scenes don't have any impact on anything either. There's a single ending and that's that.
All in all, not the worst way to waste a couple of hours, and you could definitely waste a LOT more time if you want to get the special capture scenes fair and square... but I personally don't recommend it unless you REALLY like the gameplay for this one.
