I had an alarming amount of fun with this one. It’s just simple combat fun done in a nifty way. I’m impressed with how well you managed to portray password strength via the medium of silly video game combat. The difficulty level seems to go up consistently with the strength of each password you fight, too, and I’m absolutely stunned at how well you managed to math that out. There’s even a strategy element where you have to decide if you want weaker characters at the front to let your ranged characters harass the enemy or put the explosive-throwing characters up front to weaken the enemy forces.
One little niggle, it seems like the passwords work really hard to stay in formation, and that lead me to some problems where I would direct my password to go to the right and the first letter would end up hanging too far to the left to aggro and attack the enemy while I was waiting for the later letters and the ones with ranged attacks to catch up. Had some frustrating moments with that.
I feel like the ability to fight against custom passwords wouldn’t go amiss either. That way you can get people to enter their real-life passwords and the game can show where they’re weak and then duke it out with the procedurally-generated password you get from playing the game. Maybe people can even compete to see who can find the strongest passwords.
