Proto:Terraria/Pre-Alpha

On May 6, 2011 (11 days before the final release), a pre-alpha version of Terraria leaked.

Differences

Unlike subsequent versions, only the simplest elements were implemented in the pre-release version:

There was no parallax background - only the sky.
The lighting was rough.
The only enemies were slimes - blue, green and red.
The character's standard clothing was listed as armor and could be taken off.
Upon startup, the game starts immediately.
There is no game menu.
There are no background blocks.
Fall damage is absent.
When hit, there is no indication of damage being done.
When the character dies, the death message reads: "Some n00b was slain".
The character is generated automatically from two simple templates.
Items are dropped from the player, like in Mediumcore mode. Items in the belt remain at death.
This uses an older world generation method, very different from the release version. It also lacks the generation of chests, biomes (except for forest), mines, dungeons, and other objects.
There are no debuffs or buffs, and healing is possible only by eating mushrooms.
Enemies do not despawn when offscreen, which increases slowdown.
The Work Bench and Furnace are not used for crafting, so items normally made using them (Doors, Ingots, Weaponry, etc.) can be crafted in your inventory.
Earlier versions of textures, animations, doors, and armor are used.
Music is absent from this build.
