I feel that the blocks are a bit too durable and I'm not sure how I feel about how long it can take the spinner to come to a stop sometimes, but I really enjoyed exploring the Labyrinth stage and the fun of clearing rooms is pretty cool.
Thanks for playing! Most comments fell similar. That's why I added option to stop your Spinner whenever you want to on SPACE click. I will be developing the game more to make it a good experience!
