Nice graphics and music. Nicely atmospheric. Smooth controls. So the look and feel was all good.

Puzzle design was pretty nice, in my opinion, with a well-executed level of challenge. The backtracking did not frustrate me so much as it did other reviewers because often the backtracking formed part of the puzzle itself. Sometimes you need to backtrack but only partially - sometimes you have to realise that pressing a switch has made it *possible* to backtrack. So you still have to think a bit. Brainless backtracking is boring, but there's less of that. The thing that frustrated me more is having to redo large chunks of a long level (which is brainless activity) because I died right at the end - that's frustrating.

Two complains. PLEASE DON'T PUT A USEFUL ACTION KEY RIGHT NEXT TO THE RESET KEY! Lost track of how many times I accidentally reset the game while trying to punch. And, although I appreciate this in some ways worked as part of the gameplay, forcing players to make blind jumps can get irritating - how are we meant to know if it is a blind jump we are "meant" to make, or not? It's more frustrating if you've already done a bit of grindwork to get to that point, and taking a leap of faith can cause you to have to redo it all if it's not the correct choice! I have less objection to where it is used cunningly at the very start of a level.
