@@CelestialReturner Yep. Border team would fight Marisa, magic team would fight Reimu, scarlet team would fight Youmu and netherworld team would fight Sakuya. Imagine.......
Considering TH08 was originally going to be the final game with the amount of combined game mechanics, where ZUN tried to go up and beyond such as the dual team system and scrapped phantasm stage, but ZUN probably was either too drunk or it became too popular so he decided to keep going. Just like in Metal Slug 3 where the protagonist and former antagonists working together side by side defeating a common enemy which are ironically also aliens.
Sounds a lot like Marisa's theme from Imperishable Night! Good job ;) I always liked your remixes. The instruments on the background gave me the IN feeling so much..
