Thanks for playing! Yeah, the shimmering is quite distracting, we agree. We were unfortunately not able to figure out how to fix this is the timeframe of the jam, but we agree that it is a problem that needs fixing! :)
Completely understandable, time in jams is always so limited! Not sure what tech you're using but it seems related to camera movement so a possible trick that *should* work anywhere is truncate your camera position just before rendering; IE integer only math might look like this: (CAM_POS / SCALE) * SCALE = CAM_POS; (265 / 3) * 3 = 264
