No hidden surprises this time but I can see you are improving your gameplay! That's nice! Also about the mechanism push(well not really as it's a FD block), one can easily make a budgeable(metal that can be pushed, forum here often refer it to as budgeable or mechanism) by attaching an unanchored motor to it.
I got all stars except the win block. I couldn't see a way to get it. There was a ball nearby but it couldn't be moved. Is the bot with the square head supposed to drop onto it? I had to give up.
@Chris Hester Spoiler maybe the win is not for a bot so you should... Spoiler think about the balls sequence
@Chris Hester Spoiler The stairs near the ball will also slide. Also be careful about the order in which you drop the balls.
Ok, I was able to win in seconds following @totto 's advice. A good designed level. Not sure the zapper was needed in the corner as B doesn't need to go there. But he has to be quick to avoid the other one!
Nice inviting design with enough openings to see what's going on. My B enjoyed going through the brick house and exploring all the passages. Thanks for the fun and adventure!
