Lets go with one by one!
- I love how you used UI elements spread in the game and actually we can use them as part of the game to finish the level.
-Graphics and color palatte is well chosen!
-Levels are well made! The difficulty level is slowly increasing which makes it easy to learn the game!
-Puzzles are actually fun compare to most of the puzzle games.
-Sound design fits well with the game. It is minimalist and fits the atmosphere. Every sound gives me message of what i was doing.
I will be rating few 5 stars for this project.
