[INSTUCTIONS] Up Arrow = Up Pathblock Down Arrow = Down Pathblock Left Arrow = Left Pathblock Right Arrow = Right Pathblock E = Win Block (Ends the simulation on a win) Q = Random Pathblock B = BLANK T = Traveler (Place the traveler on top of any path block. Only the first traveler you place will complete the simulation). X = Delete WASD = Diagonal Blocks 1, 2, and 3 = Control the speed the traveler takes to complete the path. U = Clone Pathblock (It takes on the qualities of whatever block was last stepped on and moves that way by 2 blocks). P = Kill Block (Ends the simulation on a lose) R = Restart Block J = Reverse Block (Clone Pathblock but backwards). Enter = Begin simulation Click to place any block. If the traveler turns green (by touching the green END block), that means it successfully completed your path. [CREDITS] I made all the code and all the sprites. This is inspired by Roons!, a marble computer by Whomtech (Jesse Locke) that is on Kickstarter. It is a Turing complete computation model, which is also marble-based. I highly recommend checking it out. It has no batteries and no screens, just a gear mechanism and magnetic tiles for the "path blocks" and a marble as the "traveler".
