We weren't taking the idea from little nightmares... I can understand why the name could be misleading. I didn't even know that game existed when we started. We were taking the idea from the gravity gun from Half Life 2. Right click to pick items up, left click to throw, just like in half life. We wish we could have added a controls screen but we ran out of time :(. We posted all this info on our game page and it says what we took the game mechanic from and where to find the controls in the mini description.
We hope you will give our game another chance!
