The stabbing attack has terrible feedback, it doesn't feel like it's doing anything. I also think that taking so many points for getting hit when the win condition for the first level is collecting 5000 points is not only far too punishing but also invalidates Red Gura's ability. It's better just not to get hit, even if you heal the points are still gone- and being able to go into the negatives means you're better off restarting than risking more hits to be able to heal back up.
We've also encountered a problem where the trident just doesn't fire sometimes.
The Kronii's look nice, and the idea of being able to switch colors and use different abilities in a fight is pretty fun. I also thought having a game about breaking into Bunkeronii and robbing it as Gura is pretty cute and could be really fun to play around with.
