Hey. Currently only 16x16 is supported. It is based on the original virtual pet models used. I could potentially see about increasing that. Would require some testing to ensure it doesn't negatively impact existing systems
Hey as part of the weekend update I am targeting a higher resolution. You should be able to use 16x16, 32x32, 48x48 etc. I would recommend keeping them sized at increments of 16 to ensure compatibility. And maintain the 12 Sprite limit 3x4 format. Testing is looking good so far.
