Away, but got a laptop :3
I saw v21 come out (and am playing it). So srry man. A few things you might wanna know about v21:
1. There are game-modes, so you technically have to choose what game you wanna play (although you can customize a game with slayer)
2. Shaders! (obviosly, although for some it might make lag, so try to choose shaders at the setting "medium"(oh btw, you can turn shaders off))
3. Play the rampage game-mode, its pretty fun: You have to destroy as many buildngs as possible in a limited amount of time while getting bigger. :D
