Game concept is a fun idea, execution does need work.
Several issues in current build with enemies getting stuck on building spots; cherries seem okay about it, but blueberries can get stuck on buildings even if they aren't created. I also saw a blueberry standing on top of a cherry, not sure if that's intended or not. The real issue is that this seems to have happened to the boss, which made him a free win.
The main strategy feature that needs to be figured out is directing units in some capacity. Since they just wander, a lot of times you have to stop and fight on your own to get to other resources.
Blueberries hit stun on you is also rather bad; it's very easy for 2 of them to chain kill you with no way around it. There also seems to be a bug where getting hit by them doesn't stop your input; you'll keep running at them even if you release the controller.
I had to ask Blooms about several things gameplay-wise to figure out what I was doing, so a little more help or grace on the intended loop is definitely in order.
I like this and want to see what it can become.
