The Hell 2 has 7 game modes that vary greatly in terms of gameplay features and restrictions. On top of that, some features and restrictions are freely configurable in config file. Like changing items in battle, running outside battle, UI elements and so on.
Ther are no time restrictions. For those who want no stress apart from difficulty mode, there is EASY mode.
Also, Belzebub got you mad because of poor balance. Was it a melee character you played? It is widely known that Rogue and Sorcerer perform better than others. Actually Sorcerer starts struggling a lot on 4th difficulty whereas Rogue advances with less effort but her ultimate weapon is Heartseeker. This effectively kills all the effort put into itemization for her regarding weapon.
No mod is perfect for anybody and some people, despite all the customization, dislike TH2. But there was a turning point somewhere in early spring this year when the mod got better and was healed from many problems. Since April, it's doing well and receives a lot of positive feedback. Partly due to wider range of options that allow to play in the way people want. Hard, challenging or good old tourist mode. We also got plans for introducing SPEEDRUN mode but looks like you would not be interested in that.
Your mod has A LOT of glaring problems that make people drop the mod (and this is me being nice with the criticism because I could be more brutal with how horrible TH2 is). Who are you to judge!? I told you everything that was wrong with your trash mod in your own thread, but since you probably didn't get the memo:
-Classes are broken, not even complete like every Mage and Rogue class. No really, Mages and Summoners are pure trash in tougher modes. Why is a summoner a worst spell caster than an Executioner!? Honestly, a lot of them aren't unique like the Summoners that just have reskinned pets. A lot of classes can't even beat Iron Man and tougher modes. If Bombadiers start with identify as a class skill, why are Identify relicts dropping for them instead of repair oils they need to clear Iron Man modes?!
-Most Traits don't really help classes at all (Demonologist's stone curse because Summoners have spell casting delays).
-Levels are VERY badly designed with either terrible mob layouts or one-hit chest kills you can't avoid, and one-hit kill chests are NOT fun let alone good design.
-Itemization for a lot of classes is horrible, and it's a nightmare to upgrade a class like Beastmaster
-You broke spells like Guardian making them useless (How do you screw up Guardian?!)
-Broken quests like Shadowfang
-The UI is somehow worse than Vanilla D1 with lack of customization, and no description of spells. I don't understand how you worsened the UI when the UI was just fine in both Vanilla and Beezlebub.
People want a hard challenging game that is crafted and tuned, not buggy broken garbage. Oh boy, Speedrun. Big whoop knowing the game is almost unplayable. No seriously, one-hit kill chests are pure rubbish. To add insult to injury, you're expecting people to pay you to make a mod worse (I get you guys need money to keep on going, but this mod is really flawed to justify any spending).
