Become lagging – League of Evil Review

I have played this game for some months ago, and conquer all of the chapter. Those days this game goes pretty smoothly. However, few days ago, I wanna replay this game and redo wnload this game, I found out that this game became a little bit lagging, especially when there are lots of spikes or flying enemy on the screen. Please fix this and I'll give you 5 stars, thanks!
