sorry that ı missed that one while play testing and thanks for the report! ı will also check around to see the issue 0-0
edit: I checked the game but my device failed to open web version while downloaded file had no problem with it. I am guessing you were playing the game with web version and sadly ı think game file is started to get too big for engine to run it which creates this ''lags'' in the game because ı also saw the pixelated sprites during my play on web before too. If its ok with you switching to downloaded files would give you alot smoother experience in game since with new upcoming updates web engine might not even open the game...
