Thank you for your sweet comment! The snakes never stop chasing. The only way to survive is to keep running away to look for rats to eat or stay and defend. Keep it pressed until they attacked, then they lose interest for a short period of time. Careful, though with multiple snakes - they can corner you quickly. The lag might be due to hardware acceleration but we aren't sure about this one. We also have hick-ups on Opera. But thank you very much for testing out our first ever game!
