Hmm. I seem to complete first puzzle but nothing is happening. Or at least I had feeling something should have happened.
Was not sure what timer is for. I guess to challenge myself.
Not sure what some of top right buttons are for. It feels like game needs to be fullscreen and perhaps it is a broken feature now due to ruffle port.
Could be cooler if rotators were dragged with pieces themselves.
Game seems alright though, especially buttons at bottom right are a nice touch.
