Lots of fun to play, especially with other people. It can be both challenging or easy depending on which game mode you pick, and there's a bunch of variety so you'll never get bored with it. Plus the developer is constantly working on new levels or modes, so there's almost always something new to try out. The retro 8-bit design also means lots of classic, bright, and colourful graphics, art, and effects! It's a simple yet addictive game, with easy to learn mechanics but immersive content nonetheless.
My personal favourite game mode is Capture the Flag! 10/10
