THE MYSTERY DOOR
You have no idea what's behind it.
Wet Paint
Paint the porch in one go.

About Wet Paint
The porch needs painting, and you only get one path to do it. Wet Paint is a one-line puzzle where you walk across every tile, painting as you go, without stepping onto paint that is still wet. It is easy to paint yourself into a corner, and the game will say so.
The porch starts as a four by four grid and grows to six by six, with some tiles already done or blocked. Level 4 adds locked sections, and level 5 is The Whole House, a big eight by six job. Endless mode trims the timer. Press R to undo a bad step. Tip: paint the dead ends and corners first, because those are the squares that trap you later.
How to play
Paint every tile in one path without stepping in wet paint.
Controls
Arrows or swipe. R undoes. Works with keyboard, mouse and touch.
Tip
Visit dead ends and corners early so they never become the last unpainted tile.
Levels
Five handcrafted levels, each adding something new, with a boss on level 5. Earn up to three stars per level, then keep going in endless mode.
