I suspect there is a reason that this level is still unbeaten at the time of this writing. It certainly deserves the tags of long and intense.
The first section is a mad dash, but make sure you push through it, because after that there are some checkpoints you can use. Watching the jem gates go down like some sort of count down timer is quite a bit of fun.
I don’t know if I’ll ever beat, it but this level has a lot of variety and is a fun testament to jem hunting. The biggest issue is there were a couple of places I got myself locked out, which was frustrating. The first was when I hit one switch and locked myself out of the normal route on the left, having to start over.
The other time was when I missed this ooooone jem. The gate opened, so I thought I didn’t need to get all of them.
As a result, I got stuck with Tiptow a bit later in the level and had to start all over.
That all being said, this is an ambitious design, and the creator makes good re-use of the space. If you like intense, precise levels, you will love this one.
