They also increased the resolution of the startup logos and tutorial screenshots, though they're filled with compression artifacts:Blue Reflection just got a patch that fixed all of the gamebreaking bugs, which i think makes it the third KT game on steam to recieve a patch.

Most other 2D assets were already fine resolution wise (though according to users in the community hub, they also have compression artifacts) except for 2D backgrounds, which are low resolution like the tutorial screenshots were before the patch:

Don't know yet if the 2D backgrounds resolution was increased in this patch like the tutorial screenshots though, waiting for confirmation on this from other users (I don't have the game...yet).
Other than this, shadows issues weren't fixed, and neither was the FMV's compression.
According to SteamDB, they're working on further patches though (version 1.02).
