thanks a lot for your feedback ! yeah whistle sounded like a nice addition in order to control team from far away, testing would be quite a pain otherwise, glad players likes it too !
about the art pipeline, we modelized everything (all assets were made during game jam time frame) into blender, then the idea was to rig and animate models to export a spritesheet then draw on top of it to have a hand made style, but it already took a lot of time to modelize and animate stuff, so we went full 3D and rendered assets from blender, imported into aseprite, added a white outline for interactable elements and exported as sprite (webp for better perf / compression) and spritesheets
at the end I realized I could gain some perfs using sprites atlases (did it for trees / grass variants)
was quite a challenge and rush but somehow got a satisfying game 🙏
