When exiting and entering the world, the top textures of all blocks that were at altitude became invisible.
Drained Ocean after flooding it, I noted with red the peak of 1675 Chunk updates, but later there was a even higher peak of 2.5 million chunk updates.The human mob model is glitched.
Unloaded chunks turned white.
The sea level in the game world did not match the sea level outside the world, sometimes there still occur "drained" oceans, see images.
The high peak.FPS counter is inaccurate on some browsers and will sometimes display random numbers.
Zooming in and out will sometimes cause a huge drop on FPS, this will cause an performance impact, and this will make all blocks disappear, and display an error icon.
On some old and slow computers, generating a new world in a huge size causes the game to crash.
The game has performance issues on some computers that do not support the correct files in-game.
When playing the game for a long time, scrolling the hotbar and when right clicking to toggle to mine or place blocks causes huge lag spikes.
The game can fail to load the player's current world and instead generates a new one. In this case, any modified blocks (even air) from the previous map are carried over to the newly-generated map, overwriting any otherwise-generated blocks making certain structures that players have built to be underground, or in the sky.
The lava's model faces are made incorrectly.
The music sometimes overlaps with other music and keeps building up to the point it is unbearable.
Trees would generate underwater, due to grass blocks spawning in the water. (NOT A BUG, but does need to be addressed.)
Differences and inaccuracies from the original.[edit | edit source]
General
Since this is a remake and not a port from the original, the code, apart from the terrain generation code which is the only ported code in the game, is completely different from the original and as such there may be many minor gameplay inaccuracies.
Air exists as a block. (still exists in bedrock edition as of version, 1.21.70)
The remake version has an auto-save feature.
Because of this, reloading or exiting then reopening the website on the same browser will load the same world and seed, along with player-made modifications, provided that the browser cookies aren't cleared.
Physics are very different from the original.
New level format.
Block IDs in this remake do not line up with the original.
The missing texture is red and black instead of magenta and black. The checkerboard pattern also has more squares being a 16x16 plane instead of a 2x2 plane.
Human mobs
They have a strange appearance compared to the original version's humans, likely unintentionally as the result of an update.
They have a different, less random and frantic AI.
Their texture has no beard, even though Steve's texture at the time had one.
They can cross the world border, revealing that unlike the original, the bedrock and water beyond the border are actually tangible and are actual blocks rather than a rendered flat plane.
They will fall through the world after going too far.
They can be spawned in multiplayer, although they will only appear on the client side.
GUI
The blue gradient, seen in the inventory, pause menu and other menus in the original, is replaced with simply a transparent gray color, reminiscent of modern Minecraft.
The red gradient, seen on the crash/kicked from server screens in the original, is replaced with the same dirt background as seen on the generating level screen in both the original and the remake.
The font is different, and is also rendered anti-aliased on most browsers. This is because it is in a vector format (.woff).
The remake uses the incorrect font (Minecraftia). This difference can be easily seen by looking at shape of the "t" letter, which is raised one pixel higher than it should be.
Graphics
Lighting is very different compared to the original, appearing more flat.
Oddly, blocks appear to have a slight shine when looking down at them.
Breaking wool and glass uses the normal grass and stone sound effects respectively. The original used higher pitched versions of the grass and stone sound effects for those blocks.
Breaking leaves plays a new sound that was not heard before in the original.
Multiplayer
There is a new menu when the user starts up the game, allowing to choose a username, and gives the user an invitation link to invite people to a server.
The invitation link also appears on the pause menu.
Other players take the same, glitched appearance as the human mobs.
The name tag above players is also more reminiscent of modern Minecraft rather than 0.0.23a.
The command set is highly limited compared to the original.
Models stored on the bottom corner of the world, underneath the bedrock layer.The lava model's faces are culled incorrectly.
Going past the world border in the X or Z direction by a distance at or below 32 blocks will instantly push the player towards the closest in-bounds location, if possible.
If the X or Z distance from border is above 32 blocks, the player will be unable to move or place blocks.
If the Y distance is above 95 or below 0, the player will be unable to move or place blocks. If they are above Y=95, they will remain stationary in the air.
The render limit for the bedrock layer is X=±544, Z=±544.
Despite not being mentioned in /help, the commands /ban, /banip, /say, /op, /deop, /solid return "Command disabled."
Iron ore is called "bronze rock" internally.
Models are stored in the bottom corner of the world, underneath the bedrock layer.
The player's nametag is a separate entity. Its position is stored approximately 1.62 blocks above the player's.
Savegames are stored as a delta; they store the world seed, size, and the blocks changed that are different from the world seed.
Lava's block model is incorrectly made: the N/S/E and Bottom faces are inverted and cull when viewed head-on. Only the West and Top faces are correct.
