It even has multiplayer with other browser players - just send your session's URL to up to nine other players.
There are only 32 different types of blocks (with most of them being dyed wool), all the original bugs are in there, although you can build as much as you want.
Specifically, this version of the game has only creative mode from Minecraft Classic, with none of the comparatively modern additions like mobs and survival mechanics - you're essentially in a time machine back to 2009. If you've got the Java version of the game, try some of the best Minecraft mods listed here!
