Because of my very high myopia (short-sightedness), I was having trouble seeing very small colored tiles on map drawn using pen size 6 in the original project.
So I replaced them with more visible 15x15-sized tiles. The "point in direction [item 'random' of list (0, 90, 180, 270)]", "move 15", "set 'color' effect to n", and "stamp" blocks are used to set tiles' colors in the remix below.
Whenever I am inspired by a cool project, like yours is, to try and remix it, I honestly don't know will it turn just into an adaptation or into a completely transformed project. So, I don't know; what would you prefer?
I'm not saying this is a bad thing, it could be an alternative to the original game for people who aren't so tuned to solving a puzzle like this, but then again it changes the game so much that a solution could be walking in a straight line, so it loses that balance.
I feel like it would be beneficial to re-increase the size of the grid, maybe even do half-steps? Increase the distance that each iteration step takes, but stamp halfway in-between so that it creates gaps.
Already more complex.
EDIT: Though I have to admit.. this brings errors at times, so maybe some extra detection to prevent the following from happening?
One way of thinking about it would be to try and make a 3-tiles jump in either X or Y direction towards the goal; if that would end up in black, then try 2-tiles jump; if it doesn't work, then try 1-tile move.
