Good concept, poor gameplay.
I really thought that the art direction for this game was spot-on. Really atmospheric, clever, original. Having the words scattered across the background was a good concept... though they were hard to read sometimes, I think that was on purpose, and hardly mattered much anyway. A couple cheap scares, a couple slow ones, overall a good balance.
The gameplay itself needs some tweaking. Well, a lot of tweaking. Jumping is too floaty, acceleration is too slow. Hitting a platform on the side not only kills your sideways momentum, but often your upwards momentum too. Water (water!) kills you. Just lots of frustrating deaths. To your credit, none of the enemies themselves are too difficult, so it seems like you were cognizant of the problems.
Really, it's a good game, well structured, good length, good rhythm... it's just about halfway through it stopped being fun for me.
