These are really good, but I don't suggest using these whenever a trick panel will suffice. Trick panels slow down the game a bit to help player react to the panel. The best place to use this is when you either want the map to be harder or if you are replicating mechanics in older maps by using this.
The tutorial is great, but I would prefer if the mechanic recaps were omitted. I think you can expect players to have completed the other tutorials or have already got the other mechanics down.
Now with those out of the way, I'm excited to see some fun maps made with these.
