This level is just a simple introduction.
Most introductions/first levels are too easy and boring.
There is no puzzle, no challenge.
The only thing I would remember about the level would be the big, open room with the panels coming out of the floor because it looked interesting, but apart from that, there is nothing new brought to the table.
Also, there is an elevator platform that raises up if stood on.
I think it should have an indicator to tell the player it is always active.

There is one thing I liked though, no matter how slim the ods of dieng in the goo-room are, you put a check-point before.I didn't test for checkpoints anywhere else.

nice work - in a P1 style map thanks for creating.
