more...Nullify (Android, Linux, Mac, Windows, Web)
Nullify is up on itch.io: http://itch.io/jam/7dfps/rate/13916
Also on my website: http://www.andrewalexanderprice.com/games/nullify/
where you can download the Android, Linux, Mac, and Windows versions.
I created this game earlier in the year, but it took me less than 7 days, so it's my 7dfps entry.
