×entrance: A bigger entrance text would do. Like give the story or explain the backgroung of the king wubba. For starters, why is a king inside a factory. Maybe he could be one of those prices that go on adventures in search for a princess. You should uncheck show exit level.

×entrance: good start, easy and you explained the "mana" in the entrance text. However you could explain it at the start of the hold. Like a tutorial. You play runescape right? Make a tutorial like that.
2E: Yes the use of custom monsters, I like using them, however. Why is the script like this:

Imperative invulnerable
label "1"
move to player
go to 1 

When I could be like this:

Imperative invulnerable
move to player

Well this is another good starter puzzle.

2N: This room is a good introduction to the teleporter thing.

×Let's see here, you have basic, secret and easy levels. And they are all marked by color, another thing you could explain in a tutorial. This room is very good. It must be hard to thing of puzzles where you can't hit orbs. But you didn't explain the custom monster in this room. I notice these thing are like other wubbas. Only smarter. They try to trap you. Blue robots eh? again the scripting is longer then needed. You should explain how they move. Like how you need to push against them to make them move. So far, this is the hardest or more difficult room, even if it is not.

× Ah secret levels, this room is okay for a secret room puzzle
