Playing Castlevania 2: Simons Quest.
I think I'm about halfway done, maybe. I'm at the 3rd mansion and have it's a bit smoother going(despite difficulty spikes) now then it was before. Though it helps that I learned time doesn't pass indoors so the mansions are the best place to XP and heart grind. The downsides of this is that it feels like I've spent more time grinding XP and hearts then actually going places because you need to buy certain things to proceed or make your life less of a living hell, especially early on.
So I do like that they tried something very different then the first game in that you spend much of the game roaming the countryside exploring and looking for dracula's bits in mansions. Now, why they're in big creepy dungeon-like mansions is not explained at all and feels like they're cribbing just a little but from Zelda 2(which had palaces that served much the same function) but the world feels bigger and more alive because there are towns are other people to actually talk to, which is cool. The downside is that half of what people tell you is either
"WELCOME TO CORENIA" or cryptic bullshit(either because of mistranslation of flat out lying to you). There's also the feeling of a early version of a Metriodvania since you need certain items to progress and know how to use them. Of course, the game doesn't really explain this to you, like what the hell the crystals do. I'm getting serious FROM vibes here and yes I know Castlevania did it first.
Unfortunately, there's another major flaw. Time passes extremely quickly in game and towns shut down completely at night and become infested with undead. This is really annoying because the only purpose of towns in game is to buy things and to go to church, so if you get there as night falls, well, sucks to be you. Better wait till morning, either hiding in a corner, running around the woods killing monsters or running around town killing undead(which are surprisingly strong in the early game). The church not being open at night is far more obnoxious because that's the only way you can heal other then leveling up, and you can only level up to a certain cap based on the game region you're inI(I think there's like like 6 levels but it takes a while to get there even if grinding).
However, add to this the invisible time limit running in the background which determines the ending you get and it can maddening if you want to get the best ending because you need to do in in 7 in game days and as far as I can tell, you need to be doing some serious sequence breaking or be completely on the ball with how you're leveling up and progressing. If you don't finish the game in 16 in game days, you get the worst ending and considering how fast time passes in the game, yeah, you pretty much need to know exactly what you're doing to have a chance of getting either the best or even the normal ending.
So while I really like the ambition here, it feels like something the NES really wasn't ready for and if it had come out a couple years later, maybe for the SNES, it might have been a much better realized game. Unless the devs just really hated the players that much, but I haven't played the SNES Castlevanias yet so I don't know if it's less hard or what).
