Sorry for the late reply!! For some reason, "1.0" seems to be baked into the game's code (even after I've tried to rename it multiple times), so you might be playing the "2.0" version already!! If your GUI looks like the current screenshots and you can play Day 2, then you've downloaded the correct version!! Just ignore the 1.0 filename ;v;
Otherwise, make sure you've deleted any older versions of the game and removed any old save files from your Ren'Py folder. You should be able to redownload and play the updated version by then ^^
