There are a lot of slide maps rejected on the hive, why do you think this one would be different?
The only triggers that do not leak, are the slide-trigger and the 2 spells, which means it hasn't been made by neither you, nor the original author (otherwise you/he would've fixed the other leaks as well) - this appears in every slide-map nowadays - though no credits have been given for that.
The triggers are also very inefficient, you can combine a lot of them.
The gameplay is still the same as 3 years ago, no new features have been added (maybe the spells have been changed a little), the terrain is still awfully empty, except for the massed cinematic doodads in the middle (whoever invented that....) and there are blizzard cliffs everywhere you look.
The gameplay is very repetitive, since there are no game modes, events, or anything else that can spice it up.
You just need to slide... the entire time.
