I love this game, but however, here are stuff I would like added to a V1.2:
-Power-ups such as the stun and speed pellet from Pac-Mania, the duplicate and jump pills from Pac-Man Arrangement '96, the Boost Dash and the Wing from Pac-Man Arrangement '05, and maybe some from PATGA if possible
-Bosses like in Pac-Man Arrangement '05
-Unique sound effects for the guest characters like in Pac-Man 99
-More level references such as the levels from Arrangement '96 and Arrangement '05, Worlds 1, 3, 5 & from Pac-Man World 2, all the worlds from Pac-Man World 1 & 3, the drawing board from Pac-Pix, the boards from Pac-Man Party Wii, Pacopolis & Hell from PATGA and maybe some Hanna Barbera Pac-Man places, aside from more Namco Arcade 80s levels
