I don’t think the gates should animate up into the air. It breaks the visual logic of 2D for no benefit. It’s subconsciously confusing to see a gate I place in one cell move to occupy pixels in the cell “above” it.
I look forward to future days introducing new mechanics as well. Can I suggest a few, based on dynamics?
- Food! The horse moves on every turn towards an attractor. Have a hay bale / giant sugar cube in one corner fall off the back of a truck / helicopter :) Horses start out dumb and move directly towards the goal before backtracking. Smarter horses path find the shortest route to the goal.
- Goals! Now that the horse is moving, get the horse into a static horse box / cattle pen cell by strategically placing fences so that the path it takes towards the food involves walking onto the goal square.
- Floods! Water encroaches from the edges on a turn by turn basis. Not only do you have to contain the horse, you also have to hold back the flood.
