Sherkan is a fun name for a cat, and fits the game well enough I'd say lol. I think this was a pretty great submission for one of your first game jams. I try my best to give constructive feedback on the games I play, but it seems like you accomplished all the goals you set out for this jam, any feedback I could give feels unproductive in that light. Learn Godot, learn shaders, 2D animations and design the whole project; I'd say you scoped pretty well for this project. Maybe too well? Nothing wrong with taking some design risks, sometimes they work out, sometimes they don't, but it's by far the best way to learn.
Hope to see you participating again!
