Development of Hyper Amy Sisters


 * most of the images below were leaked because the Zerona HQ is public, and somebody sneaked in the basement.

This is the prototype page for Hyper Amy Sisters.

Conception
The prototype of Amy (in this game) is Lisa. Amy later was picked instead because Ratzilla was getting poor sales after 1975, so they decided to promote the protagonist.

Amy was redesigned so she looked new.

Early Sprite Design
In the early prototypes of Hyper Amy Sisters, Amy's sprite was an revamped version of her Ratzilla 2 sprite.

Bankruptcy problems
Most things in the game were rushed due to being close filing for bankruptcy.

However, Zerona's money were going up due to good sales of Mudskipper Fishing.

As an result, less of the game was rushed, because Zerona had too much money to get bankrupt.
