That reminds me of Naota's Psycho Soldier X project which would've been updated for better improvement. Yours looks better. I wish he had the motivation to go back to his project, so that he could make some changes from his previous revisions.
Took a few design nods from Pierwolf - Fighter's History Revenge, with all its flaws, was an inspiration. To give a bit of distinction, I replaced the South Town map with the map used in the Yu-Gi-Oh game for GBA.
