Your game is really fun but also really hard! And I died while I was in the shop... I am not sure if this is right. :D I really like the music options and the graphic is amazing! :) Rated. Please rate back. :)
The only possibility of that happening is that you may run out of oxygen (having way too many holes for a while). Besides that, it could be a bug. Anyway, we will put an eye on it for possible bugs. Thank you!!
