This was a nice level, atmosphere-wise.
This is just hard, though? People have said my levels were hard and they weren't as hard as this!
Anyway, the music really gave it that feeling. I felt a few parts were rather frustrating--the jumping-over-the-tiles-with-the-spikes-on-top thing was kind of overdone I think, but overall it was nice I guess. Like googoogjoob said, there didn't seem to be much 'life' in the level. Only Juni and plants and maybe flickering dots were alive.
For that alternate ending, I totally used that 'wallswim' idea in Trimurti, although it seemed faster in this level for some reason.
