Wow, I really loved this! For me it was the perfect difficulty for the puzzles, just enough to get my brain jogging but not enough for me to give up and feel that it's impossible. That last puzzle especially. Took me a while to figure out that you could undo moves though, I was on the second level and constantly restarting from the start until I tried ctrl+z and went back a space, then read the description and saw that just z also did it and was relieved. Once I figured that out it was way way more enjoyable, maybe when you fall into the water in the second level just show a z somewhere on the screen? That would have helped me, I fell in quite a lot. Either way loved the game and the art, great job!
