Well, finally beat level 7. Some rooms like the one with the long curving bridge were really annoying. Well, afterwards I went and finally beat MegaZone for the fire boomerang, then I got the L4 Saber. Now, I'm in level 8... but it seems hard as hell down in lab I think 60 something with all those dman invisible enemies.
It's the lab with the Chicago music from PD. I walked into one room, and apparently I had to kill all the enemies to get out, but died instead. Then, I headed over to lab... (14?) with the MMX Intro music. I found a LEP there, but didn't seem to find anywhere else to go.
Any other entrances around and stuff? Is there an amulet-like item? If not, what are all the enemies that are invisible down in that lab?
And finally, should I be trying to get through the lab with invisible enemies?
BTW, are there any LEP's in level 9? If so, I can get all 16 hearts.
Otherwise, seems I missed some.
