I'm happy you're enjoying things!
For the clciker radius, was this an issue that it stopped entirely at too small of a size or that it took too long to upgrade? I feel like I'm happy with the Max radius size but maybe will rebalance thr radius and cube size to scale up a bit slow. I had also been thinking of adding different cursor shapes which would maybe increase the overall size that could be reached.
A talent for continuous holding is also a good idea. I'll likely make this something you can get after maxing out the speed.
Cube rotation speed could be added but I'm not sure what benefit this brings. Where its nice to have good and 'bad' affixes which can roll on things I dont want there to be useless ones which just dilute the pool.
Pericing I'm not sure I'll add. The way the game handles what cubes are clicked on is a bit of mess and I don't think it'd be an easy change. But I can add it to my list of things to consider in case it's not as bad as I think.
A relic filter would also be really handy but quite an undertaking. I'd like to add this but don't know how soon that'd be!
