You have managed to jam so many jokes and spoofs on both old-school and more modern anime, it's just so fucking good.
And most importantly it's a pretty Cool Frog.

Cheese and Rice Moony!!

Yoshikage Kira would definitely give a full 5 fingers up for this one!

Ducklings; a game where you steal orphaned ducklings to have them renovate your nest!

A little more instruction on Souls would be nice, otherwise I would have gotten further more quickly. Exponential notation being an option would also be nice. I understand that you may not be going for a game that can be completed quickly, but after beating the first 3 castles, securing gold enough to buy 100 demons as quickly as I can throw them (and still be making money), I calculated out somewhere between 28000 and 35000 clicks for me to bust down all the castles. That's assuming I continued from where I was, and using highest-efficiency units, would take an extraordinarily long time that I don't really feel like spending on a flash game just clicking even though (realistically) I've already got the resources to end the game. You might want to set it up so you can only hit the next castle up before moving on, as you could feasibly move past before needing to do other castles. Being able to auto-assault the next castle in the campaign would be useful (some kind of commander upgrade perhaps?) to continue the idle-type game-play. Perhaps upgrades there to increase the rate at which they throw minions at the castles, auto-buying minions, and access to commanding greater minions as well would be a nice addition. Still, at this point it's little more than an executed idea, not quite polished or well-thought out for your main-gaming crowd, even though it's been out for nearly 8 months.

I love the lilting bassline contrast! It really makes me think of Legend of Mana, like, a LOT.

Awesome homage!

Hoh seems a bit old for him ;)

Animation still looking good! Very true to your style.
