Hello! Thank you for your comments!
The game runs perfect in my computer but I'm sure that it has performance problems! Due to the requirements of the game trigers, rays and other useful elemnts where forbiden, so most of the mechanics had to be made calculating distances in every single frame, which is crazy for the performance but necessary in the special case! I am surprise that swing obstacle is so performance killer, I do not why and I'll investigate it just to know what is happening!
