Holy cow this is good. At first, it traps you with style and atmosphere that doesn't let you go until the end. Then it strikes you with deep puzzle design (accompanied with excellent controls and QoL that lets you focus on the solution). Yup, I actually beat the game all by myself. And boy, did I enjoyed the ending - I sat there with my mouth open for a good minute, literally. I'm amazed. And attention to detail - waving buttons animations, robot eyes reflecting last move, etc. - is also there. I have nothing to add, brilliant game, great job!
