It definitely looks like it is better. The official version is missing a lot of the H content as well. I downloaded the game from that site and tried it and remembered why I never ended up playing this back when it was released (Mega worked for me back then, but not anymore so I guess I did DL the Wolf RPG originally on here).. it has a ton of errors for me, both with the language and loading graphical assets. It's probably a localization thing.
But to be honest, even in my first playthrough I ended up skipping a lot of the H content. It's more about the puzzle game for me. I just wanted more of "The Hero Trial". Aside from my localization issues, we also discovered a few bugs in the WOLF RPG version like the Mandrake Shield not going away properly in the final battle, thus counting twice (both Farea forms) as well as being added to the final score.
Did you change your System Locale to Japan for the Wolf RPG version? If not, that's probably your issue.
I don't normally watch the H scenes either, but still prefer the Wolf RPG version for just the puzzle game--it's a cleaner experience with better options/UI, imo.
This is my best score and an image of my stats when I got to the Castle (after buying the Magic Yellow Key and going through the dungeon collecting everything I left behind the Yellow doors). In my final play-through I had enough gold left-over to use the Inn once more which could increase the final score, but only marginally because I'd have to use it inefficiently. Could have used keys a little more efficiently too to get over 1.4 million but not gonna bother replaying it for that. I ended up buying the 2 Silver keys for 1200 at the end to get into the locked area with 28000 in Hearts, but just sold one of the keys cos I had no use for it. Other notes:
-Castle upgrades were 6xATK, 1xDEF and the rest were HP. I found that the 1 Def upgrade saved a ton of HP, way more than 38600 which is roughly the trade-off, but it's possibly not necessary if I abuse the Inn more. Both of my last upgrades cost 2790.
-Did the 500 DEF->ATK trade immediately after completing Luufa's area and buying the Magic Yellow Key.
-Traded HP for Gold twice with the Reaper (costs 1100 max HP, or 22000 points, but gives 1000 Gold). Used the Gold so I could buy the 2 Silver keys for 1200 (from the Fairy) and abuse the Inn in the Castle to save every Heart for excess healing.
-Only used Fuel once (the one inside the painting) cos Ice Golems don't give their 100g if you kill 'em with Flamethrower
-Took the -50 Shield x3 path. No idea if this is the best route but my thinking was to sacrifice HP in exchange for Gold/keys wherever possible, which I did throughout the whole game. I went every route that used the fewest/cheapest keys, assuming the value of Gold in the final area would compensate for everything I lost. Because of that, I had to use the Inn once before the Castle, in Luufa's area.
If all else is equal, the difference in score for my version would be -80000 in Shield+HP, +27000 cos I can't heal after the fight but still use the Large Ointment for excess HP, so -53000 total to about 1.34 mil. I think 1.5 mil is impossible. The best improvement I can imagine would be in excess heals, and maybe a slight improvement in stat allocation, but 1.4-1.45 mil is likely the best score possible given the total resources available for increasing score.
Last things I wanna try are a totally Defense-focused play-through, though I'm pretty sure it's just worse, and to try taking only 1 upgrade in the Graveyard area, which I tried once before and it made Luluu mathematically impossible to beat, but maybe I missed a blue heart somewhere or upgrading Def makes it possible, though I doubt it.
