Man, I should have played this a long time ago. I guess I've been a bit aloof from things here for a while.
This was a really fun level, though I have to admit I spent a bit longer than I should have trying to get past the rising spike wall section without the high jump or hologram. :p I ended up needing to look in this thread for a hint on how to reach the area where the high jump was. After that, it was more or less smooth sailing to get to all the secret areas and to what I believe is the end of the level.
I think you made great use of my music here, as well as certain pieces of extraneous graphics. Your tilesets are and always have been on another level, and yet they still feel just at home in KS.
Overall, great work. Have a star from me.
