Absolute amazing game! There is so much you can do! Though, there alot of bugs, I mean first off the water on the island map is black? And the hacker issue, SSB2 has a built in hacking prevention system and I don't understand why you can't make one? But overall this is an amazing game! I can play it for hours but please take note to these bugs. And then I'll rate 5 stars!

This is a great game. I have a lot of friends on it. But there are some glitches and i have an idea for the Gravity Gun. 1. My Idea For the Gravity Gun: The Gravity Gun has improved a lot since you added those 3 options. What if we could highlight things that are connected and pick up a whole house. 2. The Boss: The boss was too easy last update and now that the boss can heal by itself it has become almost impossible because you can't destroy the healers. 3. Saving Maps: We can't save maps.

This game is fun alright,but it keeps crashing and add more stuff like trees ,plants, windows, and more walls,and more cars, put a crouch. Button and make it that we can customize the controls.plus add more entities like zombie,skeletons,etc.and more weapons and even more science fiction stuff and add more maps. Thank you for reading and there are hackers,plus ads don't work to get coins.
