Difficulty is probably 1 out of 10. use the arrow keys or swipe to move. You are the blue square and you were trying to get to the green square. The red square will grow every turn. Squares are portable boxes that the lava cannot go through. If there’s a yellow square, you must touch it before you get to the end.
Stole the swipe mechanic from @tobias_pk Everything else by me More game mechanics coming soon.
