Tips & Info
If it doesn't work, you could change it. There are two world types added: 2DCraft and Terraria. The 2DCraft world type is regular Minecraft, but it is only 2 blocks wide. The Terraria world type is a more Terraria-like world where you can jump higher, the terrain is a bit different, etc. If you think that view is too zoomed in, you may make the FOV higher. This will make the camera zoom out, and you can see more blocks. You can use creative mode, where you can fly and such. There are five different view types (two have been added with this mod).
