Use WASD to move. Click the green flag several times. If you see red squares on your screen, it means you need to click the green flag more. Click to punch/interact. Escape.
DISCLAIMER: This game includes some scary elements and themes, so those of you who aren't into that kind of thing should stay away from levels 2 and 3. Level 1 is still clean, though. I made this game as a challenge to see if it is possible to make an atmospheric horror game in scratch, but let's keep scratch a kid friendly site with appropriate content.
