JamJamma is a solo-dev pandemic project released in 2021
It started with the creation and animation of the main character and the four bosses
I also designed tilesets, backdrops, and arranged those into the mockups below before proceeding with coding. Separate parallax layers were made with Dan Fessler's HD Index painting method and then cleaned up by hand at the pixel level.
The screenshots below were taken from the fully playable final result
Once gameplay was up and running, a few extra illustrations were made for simple introduction and conclusion narrative.
JamJamma can be downloaded and played here.
