This is a neat little puzzle game with a fairly unique concept. And it's quite difficult. This game was made for high IQ individuals. When I solved the puzzles I had this great "eureka" moment. And the game introduces enough new obstacles and gimmicks to make things feel fresh. And some of them are quite creative.
My biggest issue with this game is the lack of reward and feeling of progression. In this game you solve puzzles to progress through rooms and your reward is... more rooms. There's no story to progress, no set-piece moments, no upgrades. There is a sense of accomplishment to solving the puzzles but I feel like there needed to be something more. Furthermore, I never had a sense of how close I was to a stopping point (if there even are any) and especially the end of the game. I think there isn't nearly enough checkpoints too. Having to go through several rooms that you've already mastered just to get to the one you die on is boring. I think when you die you should respawn at the start of the room you died in and the flagpoles are there to warp to.
The art is really simple and does a good job at communicating the gameplay. It doesn't do much more than that though.
I have mixed feelings on this game. I played up to around the point you see those eyeballs (?) (seen in the third screenshot).
