Huge credit to Jess Cliffe for all the work!







April, Fools!






Now in all seriousness though, I'm sorry for the lack of updates for the past few months, I've had (and still have actually) some hard times at school, so I won't be able to work very much on the game for a while I'm afraid.
Hopefully will have more time soon.
Just so you guys are aware tho, we are currently working on a bigger or more complicated update at this point (mostly it's Sandern's work this time around)
so you may expect something big in the next several months. This update is a very complicated thing to release :happymeat:. Later, folks.
