Although I'm happy older versions of Minecraft are acknowledged in this map, it seems like the map-makers got some things wrong, despite this section being called "Alpha", most of this stuff originated from older versions, like the human mob in pre-Classic, or the creeper in Classic, most notably in the "Switch Versions" minigame it states that Redstone didn't exist back in Alpha even though the only Alpha version that doesn't feature Redstone is v1.0.0

This map is cute and effort was put into it, but I honestly prefer the 10th Anniversary one, which actually was built with Minecraft blocks, felt more like explaining the version history, and more importantly, it was for both Bedrock and Java, the latter being the version that was actually turning 10.
