You should do a remake of this.. It's about 18 years old now.
1. Magus isn't an idiot, he is well aware of Lavos's involvement in Schala's disappearance. He wouldn't blame Crono for being a byproduct of what happened at the ocean palace, considering he didn't HAVE to help the time jumpers revive Crono. Glenn/Frog would have been a dramatically more viable option.
2. Black Mage.. Why? How did he meet Magus? What's his personal interest in this vendetta? Add steroids to strengthen the weak plot.
3. No background hurts my eyes when watching this in newgrounds player.
4. Zombie Crono and Marle get their revenge.
Otherwise it's a decently humorous animation. I'll bite, give you some stars. I'm sure after 18 years, you can do some amazing stuff though.
