This a set of assets I created for The Holy Whale. There's a chipset and a set of character sprites based on RM2k3 sheets, but reusable with pretty much everything else.
Following a Ren'py exclusive game jam, a fellow dev told me how nightmarish it was for her to declare all the images she needed, especially with the use of the lipsync feature. I thus developped a python routine to do this declaration automatically based on the folder tree. The link to access the showcase contains the instruction for installation and a small example demo. To the lipsync I also added the eyes shutting routine.
