0.3.1

Whoops! Looks like I left quite a few bugs in the last update because I'm a numbskull. Sorry about that! Don't worry, I fixed them all!

• Fixed Jumppads
• Achievement 2 is now achievable (see what I did there)
• Achievement 4 isn't mistaken for Achievement 3 
• the Energy Capture Cube can now be dropped
• The UI is fixed

Thanks for playing Backup!
