The puzzles may be simple so far, but they are definitely coherent and intuitive. Well, one of them wasn't, but only because I had a bit of a brain fart. I thought that the "sliding colours" puzzle and the "big globe, small globe" puzzle were just one puzzle, since they were on the same screen. I face-palmed when I looked at the walk-through and discovered that they were separate and I solved the "sliding colours" one incorrectly, lol. Maybe make it more apparent that they are discrete puzzles?
Other than that, great work, d00d!
