This game expects you to right down everything in every room and assume it is an obscure puzzle or clue to a puzzle. It should at least provide an in game notebook to give some indication of what the maker thought was important.
The walkthrough says the clues to the mummy chest are scattered around. I used the colored numbers. Wrong. The key is actually really obscure and I would never have figured it out since there are so many other simpler things it could be. The solution is Yellow, Purple, White, Blue, Pink, Orange, Green and Red. The block puzzle is a bit obscure too.
Interesting game, but I hate the way finding a single hotspot gives false color to the surrounding area. Maybe if it only shaded half the circle or otherwise indicated that it isn't actually the color shown with something other than the absense of an "x". Not sure how blue and yellow make white.
This was, at times, incredibly frustrating. Yet I felt intense satisfaction when I finally figured out every level. If hints were included I would restrict them to a vague hint indicating the shape after the initial fold (ie. Liftoff "starts with a triangle".)
The controls are kind of wonky. If you use the mouse it is very controlled but really slow, the arrows are super fast with almost no control (like slidding on ice).

Thanks for the comments. I hadn't thought about a restart/retry option...that's a good idea. I'll see what I can do.
