Use the on-screen buttons to move into the treasure chest. Push blocks over water to create a new path. Watch out for the slimes, they move toward you whenever you are standing straight across from them!
Use WASD to move to the treasure chest. You can push blocks into the water to create a path. Watch out for slimes, they will move toward you whenever you are standing straight across from them. Don't let them touch you!
In later levels, walk into a fireball to grab it, then click on a slime to shoot at it. You can only shoot straight up and down or to the side, not on diagonals.
