Thank you for the feedback and bugs found!
The QOL suggestions are especially helpful. I'll also consider how to implement multiple unit movement.
WASD movement shouldn't affect the turret if it has an aim order.
Optimizing performance is going to be a large priority for me now, it's interesting there appears to be performance issues in the menus too.
I like the idea about buttons for abilities!
Infantry is planned and the infantry system/building movement is somewhat playable, but needs a lot of polish still so I left it out for demo day.
