A really well made and aesthetically pleasing puzzle game, offers a brilliant experience if played for the first time without prior knowledge of the solutions to the puzzles. every time you solve a puzzle and find a new section to the maze that is this game you get a great sense of reward, the new gameplay styles and puzzle solving tools come later in the game and further enrich the vibrant and colourful experience. not sure how much replayability value it has, but I'll definitely replay it a couple of times now to complete certain areas, and who knows maybe in the future I'll speedrun it.
What's certain is that it's a great game, worth getting though I can't recommend at what price as different people value games differently.
Either way I'm recommending it to everyone I know.
