This was recently Super Jump 'n Bump but I had to re-do any original Jump 'n Bump artwork (which was a DOS game) so I can sell it as my own.
I created the entire forest scene in Aseprite. The smooth grass shading and the light shafts I did in GIMP using the airbrush, but the rest was in Aseprite. The leaves were particularly useful to do in Aseprite, since I could make brush shapes from black shapes very easily, and repeat them everywhere.
Here’s the teaser trailer
