This is Trials and Treachery, a Minecraft Map where you shoot mobs to advance in the Trials. However, you don’t use a gun, you use crossbows. For example, the Goldcross reloads quickly but doesn’t do much damage. That is not the only crossbow however, and there are various Alternate versions and variants if you’re willing to search and find them.

Levels will require movement skills, as Trials and Treachery is a 'movement shooter'.

Major updates adding layers usually take 4-6 months. If it's taking longer, I'm doing some very complex technological additions to the map.

Instructions 

To have this map work, you need to download some other mods. Crossbow Frenzy adds the crossbows, Enchanted Books X+ adds higher enchantment levels, Vanilla Mob Heads adds more mob heads for note block sounds and storytelling, and Raiyons more enchantments is so that custom enchantments such as double jumping are present.
