I love Monument Valley, so the moment I read it was for fans of that I knew I had to play it! I think it's cool you were able to implement a simple version of that game's mechanics. The game is a little buggy, in particular when it came to moving the character. I tried holding down the right click as well as moving the robot one square at a time, but while those strategies helped, neither of them worked consistently. Also in the first puzzle after the tutorial the robot kind of zips up ahead of the blocks when you try to scale them upwards. And I believe a couple of levels after that I was unable to get the robot upwards without it falling and resetting to the beginning, which meant unfortunately I was unable to finish the game. Still, the aesthetics are lovely and the robot is very cute.
A nice simple game that recreates its inspiration well and has potential to be a chill time once the bugs are worked out. Nice work!
