Alright, nice to see a thread like this.
First of all, let me say that I was completely surprised with the content added, not only by the amount, but also how it works, lots of community suggestions and content that's actually FUN to play, and not just some Icesantankfarmtowave999nonsense. I might not be that far yet, but I've seen quite a lot of the endgame stuff, really amazing update guys.
So far I only have a few minor complaints, but nothing really big:
The "break" animation for blocks can get a bit annoying, especially earlygame when blocks take some hits to mine, if you just want to remove grass and then place a block over the one that used to have grass, it still has the "break" effect in it. It would maybe be good if that one disappeared if a block gets placed over it, or after a few seconds if the block didn't get mined.
Sadly it's still impossible to create custom biomes for all of the biomes and some walls are unobtainable. That's the only big complaint I have here, which I'd maybe like to be added in a future update, if there are any. It's quite easy for people to break biomes such as the marble/granite/spider one, which makes it impossible to "fix" the walls and means it could lead to your world not having that biome anymore. Then there are other walls, such as the dungeon or dirt ones which have a "hostile" enemy spawning and a completely friendly version. Just having a way to craft the enemy spawning ones would be really nice, so you can't get yourself in the "I don't have this biome and can't get it into my world" situation and can import biomes into older worlds.
The other thing is the demon heart, which gives a extra accessory slot, but only for expert mode. Does this really have to be locked to expert only worlds ? You can use any of the expert drops in normal worlds(and please don't change that) and this has been something many people have been asking. Between items that fire super fast and deal 200 damage and this, you have to question if it would really be that broken to allow everyone to have a 6th accessory slot on normal worlds.
I'd really like to see a "toggle visible accessory" option for the vanity accessory slots, as it's currently impossible to have vanity wings only active while flying/having wings+vanity wings+cape equipped.
Please don't misunderstand this, I'm really happy with this update and all you have done and don't want you to get upset about this post. Never expected that the dev items, which were a topic that caused a lot of heated discussion would be available to the public... I'm crying right now
, in tears of happyness, I'll have to build a shrine for those sets now, to pray to them xD.
