The graphics looks pretty ok, but it's the only one positive thing I see about this game so far. Character moves so slowly that it fits perfectly with this slow, shallow and brainwashing music and those snail-enemies. This slowness makes me bored pretty fast. It gets a bit more interesting later with those black levels, but they still are slow.
In the first level hitbox is not only not hidden (as you noticed yourself), but also moved to the side. Also there's a weird thing with the animation - when you move to the left the gear looks like it should move to the right and vice versa.
Hope it will be better in the future though.
