Ardy Lightfoot is a platform game developed by ASCII that was released in 1993 for the Super Famicom (Japan) and in 1996 for the Super Nintendo (USA and Europe). It seems that a beta version of the game was somehow leaked online, as we can see many videos from this early version on Youtube. More info on the differences in this beta are available at Flying Omelette!
Ardy’s speech bubbles are differently coloured, and Nina looks different.
The prologue stage is completely empty of stars
The push block gets a new graphic in the final, presumably to indicate it can be pushed and isn’t just scenery.
The beta presents a chest with a bomb, while the final does merely places it next to the wall and requires being moved closer.
The tunnel you fall into requires awkward walking to venture through, while the final makes a little more sense by having you slide through it.
The beta version of Scene 2 is very unfinished and different
Catry has all new sprites, but they’re pretty bad in comparison to the final ones
