It was worth the wait.
Welcome back. You sure took your time with it, I don't blame you. You've been teasing your fanbase during these 16 months by showing us the first 3 completed scenes and kept everything else top secret. At one point I even thought that you cancelled the series altogether after ep. 6. Thankfully you decided to continue with your story.
Most of the fight scenes and dialogue were great as usual. The scene where everything was turned 8-bit felt a bit tedious at first with most o the dialogue, but you were able to adapt the 8-bit effects to your own style during that fight scene. In the end I think the "minus world" concept was quite entertaining when Metal Sonic finally showed up.
I'll be looking forward to the next part, so good luck with it.
If you have pride, you must keep this son of a bitch going!
