For those who know the Aero the Acro-Bat series, this is a spin-off starring Aero's rival, Zero, who is a squirrel as you might know from the title. This game came out around the same time as Aero the Acro-Bat 2. There never was a third game in the Acro-Bat series, even if the second one's ending hinted to a sequel. A GBA version of the game shown in this video was planned, but cancelled. Aero the Acro-Bat has a version on the GBA. By the way, this video was made from the SNES version, but the game was also released on the Sega Genesis/Mega Drive, just like Aero the Acro-Bat 1 & 2.
