Thank you for your interest!
About stealth is a great statement. Can be used as a quote or slogan :)
I specially made barrels above a jump. In my opinion, this added an element to the puzzle. To jump over the barrel, it must be moved to the box. They can also pinch opponents. If you guess their trajectory.
Thank. There are such plans, for the most part all the necessary scripts for constructing the levels are already ready.
