Rare GBA pirate made by Sintax apparently. It uses the same engine as Crash Advance 4 and Rayman 4. This game is very buggy, from the sound screwing up around certain enemies to clouds disappearing when they go off screen. I can't seem to find a way to even beat the game either, the last boss doesn't appear to take damage and he eventually disappears.
This game also was ported to the SNES, or that possibly is the original version and this isn't. All I can say is the SNES one is much better, and has more levels.
