Thank you so much for the feedback and the kind words :)
The Grove (and the Barricade) not having a radius is actually not a bug but a less than ideal decision on my side. They both have 0 radius before upgrades, because they don't really do anything with it, and the show radius function display a weird dot, aka a size 0 circle, so I removed showing radius all together when it's too small. I did notice how annoying it is to see what is selected, but forgot to actually do anything about it... Should be a quick fix show their range from the start, I'll have it added at the next update.
Lack of free time is a little of column A, little column B. I'm learning Japanese as hobby, and am taking the JLPT at the start of July, but am kinda way behind, so most of my productive free time is going to studying. It's a hobby, so fun enough, but being behind is stressful xD
Either way, once the exam is done I'll have a lot more time to focus on the game.
