An excellent and challenging map. I appreciate how devious and distinct each encounter was, even with a relatively small monster count, and the rocket-centric combat kept things nicely fast-paced. I didn't find every secret but I got all kills and items.
I was playing with Nugget Doom and the game crashed as I entered MAP02, but I figured I had seen everything there was to offer, and had no other problems.
I hope you'll continue mapping, this has inspired me to do the same.
