I just wanted to let you know I have updated the construction kit. There is now a blue laser that turns off after being touched. It's based on the disappearing block concept you shared here, so thanks again for doing so!

Thanks for sharing. I like that break-away block game mechanic! Also, if you are interested, you can add copies of the yellow "?" block in the locations where action arrows can be placed for a successful run. They will show up when players use the "?" button if they need a hint.
