I think I got to the last desert temple level, the one with timed waterfalls, but I didn't know how to find the key after long time checking out every corner. The last blue box didn't seem to go up enough to destroy the water below the door.
Anyways, I really liked the concept of "The floor is water", just the base idea is super creative. The mechanics of the different elements like the green block and blue block are good and can make a huge possibilities of puzzles. I also enjoyed the dark vision gameplay in the temple.
The level design was good too, apart from that last part of the level I mentioned were I was super lost.
One thing I tweak is the color of the desert temple platforms since they look identical to the background and can get hard to distinguish.
Overall, great submission!! Kudos!
