This is a 2D puzzle game called Cut The Rope: Experiments. You only need to use your mouse to play it.
Physics and rope are the main parts of the game. A string is often used to hang the candy, and it needs to be cut to move it around the level. Gravity and motion affect the candy, which makes it easier to move around. The levels are enclosed, but they don't have edges, so if the candy goes off-screen, you lose it and have to start over. Some risks can break the candy and make you start over.
If you click the left mouse button, it will feel like you're tapping, which is how you move the tools around the game. Hold down the left mouse button and drag it to cut things. In each level, the goal is to get the bright candy to Om Nom's mouth. A level is complete when all three stars are collected.
Have fun and good luck!
