Hellmode ~A Hardcore Gamer Becomes Peerless in Another World with Retro Game Settings~ヘルモード　～やり込み好きのゲーマーは廃設定の異世界で無双する～

Just under halfway through the current chapters (at 54) and it's pretty good so far.
He spends a lot of time working out how things work, which is kinda refreshing given how generally there would be a system which would explain things. Instead he has to do trial and error and use his own deductions to figure things out.

The only kinda strange thing is the fact that in some of the earlier chapters he sometimes talks about him doing a speedrun. I know that when JP mentions speedruns they generally mean RTA runs, but it still doesn't really make sense here as it is in no way a speedrun. He chose a difficulty level that makes things like 100* more difficult for him and it takes years for him to level up his skills.
Maybe its just an issue with translation or some other difference in understanding.
Luckily it seems to have not been mentioned much at all as the story continues on and the quality is still pretty decent as of now.

a harem tag but no romance tag, does this mean that he's going to be followed around by many beauties but won't get involved romantically? Typical JP sh*t.
