I really liked this game, was quite difficult though and could have done with some explanation on certain parts, like level 3 - I wasn't sure what was happening when you go through the water? And how to reverse the effect, I ended up having to walk around the first water bit on level 3 and activate the water on the 2nd bit, I'm not sure if this is the intended route?
Also wasn't able to finish level 4, but really enjoyed level 1 & 2 so top marks for that :)
