There has been an absolute abundance of minion management games in this jam, even reverse-survivors takes on it specifically, but this is an outstanding approach to the concept. The ward-area around the "heroes" presents a unique threat and a tangible form of progression that a simple life bar wouldn't. Ina's physical presence makes the player feel, well, present!
Also Ina is very cute and I want to give her a hug.
Edit: Checked out your profile after rating this, it seems that we're cut from pretty similar cloth :p
