Played almost all maps. Video:
The game is interesting and the concept is fun, but the controls need work on them. I had issues while manipulating pieces, either placing them or rotating them. I think you need a better way to handle these.Having the whole track setup but being one piee short and needing to start all over doesn't feel great.
Sometimes I wanted to see where my pieces where but it was impossible to tell where without having to lift them up.
Last level I played I felt completely lost. From a glance the last level looks like it takes an hour. I think that starting with some pieces already on the board, stuck in place, would help to guide the player.
