Found a bug: Game freezes after you finish a survival run. It's showing my time (16:10) and clicking does nothing.
Also, after i reloaded the page, nothing has saved, so i lost around 250k gold, wich is sad.
But anyways, its a really good game!
Level 30 is the hardest. Took me about 350 deaths of my 420 to deal with it. If you get throught it, you can do all the other levels. Level 30 should have been level 40
 "Sentry Knight 2"){kind=icon}
 "Idle Mine"){kind=icon}
 "Give Up"){kind=icon}
Thanks for reporting this, pthenine. Currently looking into this!
