I am apparently a bad enough dude. This an easy contender for best concept in the jam. As fitting her canon, Hecatia's 3 bodies lend a huge amount of power that would make the game trivial... if you could control them efficiently. And its fairly deliberate the devs granted the raw power because no one is doing this efficiently. Yet with three bodies and free reign to decide what to upgrade on who, the player is free to experiment with their own solution to the three body problem. I favored a slow and steady approach, setting up 2 Hecas as turrets to counter spawns and using the third to kill the spawner itself. And then halfway through wandering ghosts show up to challenge my playstyle and force me to adapt. I have seen someone else stack all the upgrades for a super Hecatia, trying to narrow the control issues. A game that gives tools to the player to use and leaves it to them to decide how to apply them is ripe for emergent, engaging gameplay.
Besides the gameplay, the UI is very well done and it needed to be with how the amount of information is needed. Lighting up the hats of the active bodies is very clever. Also clever is the grass around fairy spawners. They warn the player a spawner is near before they are on screen, and the withered grass marks cleared areas. It is actually a shame the later spawners don't have a similar callout. The sound work and other visuals worked well enough to support the game. Nothing stood out, except maybe Hecatia's chest.
For such a strong base game I would have liked to see more of a story and depth to the characters. I wanted to play with the bombs more, but with them being the only apparent source of health recovery I felt obligated to save them all for Earth. Maybe Junko could restore some HP?
One final note- whoever designed that room with the wolf spawner and a ton of yin-yang spawners in a tight twisting corridor, you are an absolute fiend and I want the fifteen minutes of my life back I needed to clear it with two of my Hecatias at 1 hp.
