Thank you very much for the feedback, indeed there were some issues with the spawners of the enemies that were causing a terrible lag. I have uploaded a last patch (Devlog Last fixed)
The truth is that it is an ambitious project for 2 weeks, but thanks to your review I will be able to fix it in a few days
I have not been able to replicate the audio problem ( I focus on it ). However, I have separated the help objects more so that they are not activated at the same time.
Any bug comment it. It will be well received.
Thanks a lot.
