Cool game.  The tutorial seemed cool.

The alarm clock bug is real

I sometimes wonder, how in the world do people come up with such interesting ideas

Ah darn, I seem to be getting the same bug as others, where I can't start the reaction on the alarm clock level, but it's really a shame because this is an excellent idea! Even the tutorial got my wheels turning about all the creative challenges you could make with this. Would love to be able to play a more complete version someday!

The tutorial was really fun and it seems like a great concept but I also can't get past clicking 'start reaction' on the alarm clock level

Not bad, but certainly could afford to be more intuitive. I don't think I really even got past the first level because the ball never started rolling after hitting the "start reaction button". Honestly I'm surprised I even got past the tutorial because I didn't realize when it said "hold down the mouse cursor to move the camera" it meant the right mouse button, not the left one.  The concept of dividing the tutorial between different rooms was a good idea though.  It assures that the player has some idea of the basic controls before they start the game.

I think the concept would have been really cool but I couldn't get it to work. My first time playing, clicking the "start reaction" button just immediately gave me a game over, while my second time, I got through the tutorial, and then on the alarm clock level, clicking "start reaction" just made an alarm clock sound without the ball moving anywhere, again making me stuck. Also, the timer never started counting down and was just stuck on 15. I really like the theme, the placement controls are good, and think it could be a super fun game - just needs a little bugfixing!

I loved making dominos when I was younger and this captures it quite well!
