- Fixed issue with grenades falling through the floor

- Added the cost of the item, so you're not blindly spamming hoping you've got enough points.

- Added Challenges that enable a buyable ending.

- Acknowledging that this map was intended to be a survival only with no escape, I set the cost of the buyable ending at 50k.

- I will continue to correct any bugs that I come across or that are reported. I am still working to locate the source of the powerup sound that can be hear under the water.

Please continue to provide any criticism or improvements so I can improve and make better maps
