One issue that came up was on the level you get your final ability (I want to believe it was 30, but it could have been 40 ;0), using the shift ability caused the game to crash due to there being no platform to teleport to. Obviously it wasn't needed to use it on that level, but accidentally clicking it was all it took for my browser to 'splode =(.
I'm not sure if it is just me or not, but it feels like the Stadium just got a lot harder to keep up with =0. I tried resetting my points and everything. Meh, maybe it's just me ;0.
I must say that the Epic Christmas tree is pretty amazing =0. 23,000+ Harvest value every 30 minutes and it stays active for more than 400 days worth =D. I think the only tree that tops it in my mind is the Mystery one. This game, despite the last few Idle games I've played has really taken me over in interest =). For Tukkun to put time into continuing to put in new features is amazing! Keep up the good work~
