Ran across your game from a r/gamemaker Feedback Friday thread and thought I'd check it out as I'm a fan of building games. You have a promising start!
After a certain point on 0.53 the game started stuttering badly, unless paused - unfortunately I don't know what I did that broke it; I thought it was maybe clearing all the message board notifications but I tried that in a new game and it didn't replicate the behavior.
