first off, thanks so much for building & maintaining this tool! i've used it for every Bitsy game i've made and it's been an absolute lifesaver.
i sometimes encounter the following issue: i upload an image to RGBitsy, see that something's a bit off, go back and fix the image, and then try to re-upload the image. it seems like RGBitsy doesn't pick up the change since the filename is the same. it's a tiny issue, but i'd appreciate being able to re-upload!
