Playthroughs and Hints/Spoilers
I've uploaded a couple of playthrough videos for the game and a spoilers and hints text file. Unfortunately my laptop runs a bit slow while I'm playing the game and doing a screen capture at the same time, so the videos show the game playing at about 20 fps, whereas the target is about 30 fps (which runs smoothly on my laptop otherwise), so the game appears a bit slower in the video than it actually is.
The spoilers and hints file provides details on how to beat each level if there's something someone gets stuck on. I've been involved too closely with each level for the whole week, so I feel like I lack perspective on whether they are too hard or easy :).
