At first glance a basic sprite hack of the game Armadillo.
Sprites of Mario from Super Mario Bros 3 was inserted in place of Armadillo.
Unfortunately that is where it ends with the original rom/cart.But a few years ago somebody actually went on and edited a lot more.
Basic enemies were replaced by Goomba’s, Koopa’s, Sniffits and more backgrounds were edited aswell as the intro screen.
Unfortunately the bosses stayed unaltered.
The gameplay itself is a bit ackward at first, especially if you expect a Mario type game.
You can’t jump on the enemies like normal Mario, you have to transform in a ball to be able to kill them.
Overall a good hack wich I enjoyed playing.
