I just updated  Life of a Battery!  It's still not finished but I feel like it's definitely almost done.  

Here are some of the things I've added and changed so far: 

• More levels!  I believe I've gotten it to around 22 levels.
• Updated menu!  I've removed a couple of the options on the main menu and replaced them with a lot more, such as an option to skip to checkpoints in the game.
• Updated visuals!   I've made some improvements on the graphics, such as replacing the out of place, non-pixel fonts with pixel fonts more fitting to the game.

I don't currently have an update for the Linux version, but if requested I can make a build for it.

If you've tried out the new update, feedback would be greatly appreciated!
