I’ve never played Asuna, but the research thing sounds like it’s copied from Terraria’s journey mode. Research enough of an item and you can duplicate it endlessly, as an alternative to a more traditional creative mode.

Sounds like there’s more Terraria influence too, like slimes holding items and the lack of swimming. I wonder if you’re supposed to find boots of water walking or flippers for swimming, so you can cross water easier.

I don’t have a problem with that. Terraria has a lot of great ideas, that’s why so many Minecraft mods (and apparently also this) also use them.

Thanks!
