I liked the first version and ditto on this one. I'm not quite done. I'm sure I haven't found all the secrets.
the beavers are new right?
As for the music I find it highly appropriate. Some level makers use music that is sooo jarring and loud that it makes playing the game unenjoyable. I guess it's all a matter of taste. However, in my mind, your music choices are more in the same vein as the original developed by Nifflas.
Same environments? Maybe the poster was playing another level.
This is definitely not a "meh" level. The proliferation of shifting, trickery etc in recent months jades people I think. When a level comes along that harks back to the ks roots and doesn't have all the newest bells and whistles, people I'm afraid, consider it boring. I don't.
Great job.
