Technical stuff:
Bad codebase that is a pain in the ass to extend/maintain.
It's Flash which is dead and shitty and it would be a massive undertaking to redo everything in JS.
Adding backwards compatibility for any new features would be more work than creating the systems for the feature...
You can't import yet.
IIRC the only things that importing will effect is the history of the fabled champion and Taoth. So, Kasyrra might reference the ending from the save you imported, or the champion may be male instead of female, etc.
We're only doing minor changes right now until we release the Forest. After some Forest content is released (which means easier encounters to grind and a 3rd companion) and companion AI is tuned, if it still feels bad we'll explore more options.
Right now Journal UI, Options UI, and the entire TF/alchemy system (UI included) are the top priorities. We'll probably pepper in some new actual content to keep people busy too.
