Who knows if that extremely eloquent title isn't already taken...
Had a jab at an isometric-style game, I think the core gameplay is alright, but I'll probably be using the whole structure for something different.
To play the linux version, you'll need to have Löve installed.
For ubuntu have a look at Löve's official website: www.love2d.org On Arch linux, just install it with "sudo pacman -S love"
If your system doesn't understand what to open the file with, after installing Löve, just start the game from the terminal, with "love survive_ball.love"
