Hrimfaxi sent me a very, very awesome map for SM88. Very tough, haven't beat it yet. Download the pack just for this map, it's better than his last speedmap IMO.
I have to apologize for my map, I spent a lot of time on this wierd maze-elevator map that I could never get to work right, so I had to make a cheap "tricky" map in 30 minutes.

File is in
.rar format, so if you have problems I can re-upload it to .zip format if anyone needs it that way. Have fun!
