Yes, I tried it a few times, and it's the same. All enemies are animating, but only a few are active. I tried it about five or six times. One enemy is allways active:
At some point, there are two platforms. One goes diagonal, the other one vertical. From there, I walk to the left, until I can go no further, then I go a bit down. There, in the corner is an enemy that seems to be active all the time. Then, more to the right are two enemies, and one of them worked the first try, the second try it didn't work.
If I clear the level, and restart (choose level 1 again), all enemies are active.
I didn't noticed it as a bug at first, because you mentioned the game wasn't completely functional.
