Hi guys.
First I want to congratulate you for the great job you have done. I love your game and I have already completed it, I am looking forward to the next update.
My problem happened when I was playing the last level on hard, after an hour of playing the phone got very hot, I saw how the screen started to get damaged and I felt like my hands were burning a little bit. I got scared and I put a wet cloth to cool it because I felt it was going to explode. Now my phone is completely dead, it is very sad.
I think they should adjust the generation of enemies in the more advanced levels because as there are many that attack you at the same time this makes the phone get very hot. I am a software engineer and I can think some strategies to solve this, but you are cracks and I know that you will find the best way to solve this.
I hope to be of contribution for the continuous improvement of your project that I repeat, is spectacular.
