Not played a game in a LONG LONG time that offers tons of fun, replayability and humour, but when a friend gifted me this I had a feeling that this game was a MASTERPIECE... and I was right.
I played with two other friends and the experience was absolutely amazing, I was shocked on the Price mainly and how low it was for a game with such quality (It is ONLY in ALPHA too!). You become extremely focused and attached to the game, focusing on beating your opponents on a variety of maps, using powerups on each other, taking different routes and constantly gathering more skill each time you play and that is what I enjoyed the most about the game. Each time you play it, you feel like you are getting better, leading to you becoming attached to the game. It is also a great laugh with friends, using powerups on each other and just being the biggest troll ever. What amazed me was how easy and simple it is to create maps, also the game is workshop supported! Create it in-game, share it instantly to workshop for all of the community to see... it isn't as complicated as map-making when it comes to Source Games (Garry's Mod, Team Fortress, Counter Strike). There is also ranking if you feel confident enough in beating other players and being the absolute best speedrunner.
The only downside is that the Keyboard Controls are yuck... I have began using a Gamepad and find it easier. You can customise the controls of course but I just cannot find the right setup for me.
Just make sure you have friends to play it with!
