I want recipe sorting/filtering.
Also item sorting was a bit weird, too. It wasn't clear how to sort/filter to the equippable items versus materials.
I hate spam clicking so I just used an auto-clicker instead.
I think without an auto-clicker it would be a pretty slow to progress game, but with auto-clicker its slightly too easy.
I think spheres should be accrue resources or have longer countdown. I don't want to feel the pressure to check back every 1-2 minutes to click on them, even with the collect all upgrade. Also the pop-up about the collection is a little annoying since I have to click close on it, better if it auto-closed like a toast instead of a forced confirm dialog.
The last 3 bosses were difficult even with auto-clicker. I noticed the militia people took a lot of resources to get the last level, like thousands of cores, so I didn't bother with that yet. I assume that was an intentional soft wall due to it being WIP.
Skills felt a little under-powered to me.
I think an auto-fight unlock would be nice to have.
