Hi! I just downloaded the demo of this game but ran into a couple of problems. For example the down key didn't work (for activating the levers or saving the game etc) and I didn't know how to quit.. Esc wasn't working for me.
Apart from that I really enjoyed the first level - the music and sound effects were satisfying and the level design was fun. My only criticism is the camera. It kept switching between fixed and scrolling somewhat randomly which disturbed the gameplay a little.
