Gap Monsters is a new, and exciting, perplexing puzzler that challenges you to kill all of the monsters on each stage by moving both white and black boxes across the screen. While the gameplay seems minimal, this is definitely a very challenging puzzler and if you’re looking to give your brain a work-out, this is the game! There are a total of 45 levels and with Newgrounds file sharing feature (which I believe is new) you can play nearly 1000 player created levels, made by players like you. The game is by Nutcasenightmere, the developer of the very popular :The Game: series. Anyway, be sure to check out this very exciting new puzzler, now on Newgrounds (and featured on the front-page)!

Here is the official walkthrough, which can be found on Youtube:
