In new to Pico-8 so maybe you can tell me if I'm doing something wrong.

In the code below, the sprite and the squares render just fine, but the circles only appear when the camera offset is exactly 0,0(whether by calling camera() or camera(0,0) or by never changing it).

The manual doesn't mention any incompatibilities between circfill() and camera()

I'm using Pico-8 0.1.0 for windows
