I played through this again last night and found a new "Secret Bonus Room"--
this game is full of places where you can duck for 2-4 seconds and get warped somewhere else...I didn't realize how many were documented in the Cheats section, but I'm pretty sure I found one that isn't listed on level 3.

I meant to track down the "random warp" in Level 3; I'm pretty sure it involves jumping around like a radical maniac on one of the large clouds below a gravelly cliff, then you get spirited away in mid-air.
