My feedback: Building the maze takes too long. Maybe turn the play button into a fast-forward button when the maze is being built and solved. The dark mode colors are pretty bad. When you click and hold, it should turn every square the same color until you let go again. Right now it toggles every square you pass over, which is confusing. When you move the start and end, it removes walls from the board. Isn't Dijkstra…
Ye the colours aren't great - design skills have a long way to go ! Fixed the start and end nodes bug and will look into adding the fast forward button and inverted binary tree maze. Thanks for the ideas !
