Few things are still wrongly translated... not really suggested to pull.

What is wrongly translated?

[Yuuki2012]

For example these things:

  helpValue: "Zie de eiland level waarde van het blok in je hand"
  de -> het
  
  requiredPointsToNextLevel: "Je bent nog [points] punten nodig om level [next] te worden!"
  bent -> hebt
  
  monsterspawning: "Sta het van monsters wel of niet toe"
  mist 'spawnen'

[Yuuki2012]
