Thanks for the feedback, I agree the dying part is harsh lol from testing I did feel you need a bit more room as its fading / shaking to allow for urgency and more importantly time to get to the surface. I am keen to add this, I just ran out of time for all I wanted, like designing the player properly with anims too.
I noticed two shop related glitches at 12:30pm in NZ I had 10 hours left but work and sleep next day. I am not sure why the shop only lets you visit (and buy) once - I will fix this. I felt if I had 2 more hours I could have straightened that out.
Again thanks for the feedback I will also look into / try out some of your other suggestions :) - I cant believe what some of the others accomplished in such a short time!
