A very underrated gem. Unfortunately, I couldn't get past the first level with the 'power' block, the gate just flickered and I couldn't pass through it even though the block was in the right place - maybe I was doing something wrong. The graphical style was wonderful and characteristic, and the puzzles were addictive and satisfying to complete. I loved being able to hit R to restart quickly, and I replayed some of the levels several times before I completed them - which was a lovely challenge that kept me coming back for more. The puzzles and style are very well designed. I would only change the 'Next level' button being a mouse click. It was a little annoying having to take my hands off the keyboard to move the mouse. Try and keep it 100% keyboard control - again, I may have missed something here. A really nice entry!
