The old Java Edition logo is pixelated which aligns much closer with the Legacy Edition artstyle (and the artstyle of Minecraft in general!)

Here's a comparison of the OLD vs NEW logos, notice how much more natural the old logo looks, it fits in with the rest of the title screen while the new logo is jarring and dissimilar to every other element of the title screen

As such, it is only appropriate that this mod replaces the logo with the old one (or at least has an option for it in the settings)

The logo won't be modified by default, sorry.
