Cthulhu Saves the World - Beaten. Game time was about 13 hours (pretty short but no shocks here), levels were about 41. Also beat the optional superboss(?) at about Level 35. Bosses got less interesting as the game goes on, I settled on a party of Cthulhu/Umi/Sharpe/Dacre, open every battle with Regen All then pile on more buffs while Sharpe/Umi buff themselves and tear into the boss, with Cthulhu either using Protect or adding damage depending on the type of fight. Siren's Call to call down an unholy blitzkrieg at the end. The fight against Dem at least puts a ripple in this in that you pretty much have to use Siren's Call earlier and there's a time limit effectively, ended up using the Cursed Sword there and dealing with improved offence throughout so I could blitz him better. Final's not bad exactly, things would have gone badly out of control in a couple extra turns probably, but still felt like a predictable affair. The maingame bosses leading up to the final were bad on the other hand, especially Dagon of the "I'll waste all my turns summoning if you kill my support, btw said support is OHKO-bait". Oh well.
Randoms were pretty much a joy throughout. Against my expectations they started picking up again; the last three dungeons were considerable steps up. Deep Ones were especially painful opponents. For a while I tried to MT mow everything down but after I got Death I switched to ST destruction using Death, Wind Strike, and Cthulhu's HP-Bane-enhanced Dark Strike (or whatever else in case of resistance). GT options got way worse as the game went on, not enough more damaging than MT (and there's almost always at least 2 groups) and much less damaging than ST.
Lategame PC notes~
Cthulhu: Still goes through points where I kinda wanted to bench him. He's generally not as good a fighter as Umi/Sharpe and the magical side really doesn't seem to keep up although I stopped trying to build for it. Anyway his damage was a bit spiky with vulnerability to both HP Bane and darkness and at worst he offers Protect, as always. At best, he has great offence and gets the best combo finisher.
Umi: I kinda admire what they did with Umi, she has everything. Great enemy control, great physicals (although they need some setup in the form of insanity, status, or a turn on the str+100% self-buff), decent MT magic, good speed. She might be MVP but her durability is awful, worse than the mages. Still generally worth working around. Oh yeah, and Siren's Call is kinda broken, but at least it's restricted. Totally great for bosses, randoms depends on if you're going MT or ST.
Sharpe: Continued to do exactly what he did all game, and do it reasonably well. His MT magic takes a dive but otherwise, still smashes things, Wind Strike could OHKO some reasonably durable and very annoying randoms late.
October: Queen of MT damage (double-boosted Void is sick), and once she gets Death she's queen of ST "damage" in randoms, too. Of course she's slow and on the fragile side. Doesn't offer much for bosses besides Girl Power and Fragile.
Paws: Man, I kinda figured he was a bit of a jeigan. Just gets bad as time goes on. I have no idea what his niche is supposed to be; Dacre totally steals his healer role, he isn't nearly the fighter Umi or Sharpe are, and I don't even want to talk about his meagre attack magic options. I guess he has stun or something (though only the ST version is accurate), you could probably do some cute things to bosses with Fragile/Paralyse/Stun Strike or something.. And uh he's fast! I probably didn't build him as well as one could but still.
Dacre: I predicted he'd surpass Paws and indeed he did. The various hymns, not to mention his regen being much better, push him ahead, which was expected. Less expected was the fact that there are no super-fast bosses late so either Slow Strike or Speed Hymn can reliably get him to go before most. Also, Holy was a pretty nice pickup, the MT version made him part of the MT blitzing team and he actually had some use in randoms after all.
Ember: Very tanky, so if your goal is "have Cthulhu and two other PCs attacking" then he's your man dragon for protecting everyone. Also has some not-bad but quite limited MT physical damage, and otherwise doesn't do much. Well, Volcanic Aura during a brief window where Fireball is decent damage for both October and Cthulhu.
Dem: Didn't use.
There's not too much to say about the game that hasn't already been said. Its gameplay is fun and obviously has some love put into it, even if there's some tinkering I'd do with the enemy balance at points (although I assume it's balanced for a more casual player on NM while HM is just multipliers, may be part of it). The game has lots of good design decisions. HP healing after battle, MP regen tied to battle speed, saving anywhere, enemies who are tough enough to demand you think about how you face them.
I just wish the writing had kept up... at first it felt like a very fun parody of RPGs coupled with the utter silliness of Cthulhu trying to be a hero and some fun fourth-wall breaking. Later on it just feels like it's going through the motions and what little writing there is is just an excuse for gameplay. Instead of parodying a Dragon Quest it becomes one (with way better gameplay, and freakin' Cthulhu replacing instead of a silent main, and faster cutscenes, and... okay, it's better than Dragon Quest). Dacre's joining pretty much sent up huge warning signs of the problems, it doesn't really recover from there.
There's some polish concerns as well, though that can really only be expected from a game made by a devteam of I believe three. Most things to do with equipment (the shop screen, the equip screen, the fact that there's no indication of which weapons you have multiple copies of) felt a bit awkward and dated. There are occasional typos. But generally, nothing too major here. Dungeon design is quite maze-like, which I don't really have a problem with but I can see how some might. World maps as ever annoy me more, I don't have the patience to explore them fully so it felt pretty random if I found those little optional dungeons or not.
Not sure where this one ends up being rated. 7 or 8 probably, it's quite unique and I'm still not sure how I compare it to high-budget, writing-heavy games which it resembles not one bit. What I know is I will come back to it at some point, probably play Cthulhu's Angels at the very least.
