Really nice game, I liked it very much (I was playing on pc).
Just... I had problem when I was in that jumper/hoovercraft when it touched ground I had to repress (release and press again) side (right) key.
I must admit, I skipped that level (edited save file), it was too much overwhelming on my nerves

(Co-worker passed through, I didn't.)
I almost forgot shame it hasn't pixel perfect collision detection (I didn't touch the spike, just square of my characted touched square of spike and I died).
But it was game I really enjoyed.
