Neon Madness Uprev

- Fixed some of the collision layers

- Fixed pause menu not always functioning

- Fixed not being able to start a new game after going back to the main menu

- Increased play area, as there's no UI content outsie of it yet - might change later

- Added randomized enemy spawn locations. The enemies will not spawn on top of each other, however, at the moment there might be some lag at the start of the waves when it is looking for empty positions to fill. To be corrected with a later update.

- Changed some sprites to be slightly more aesthetic.

- Adde a "powerup" system, with randomly spawning collectible items. At the moment these are there to increase/decrease pad size, and one to refill "lives", as the first boss can wear them down quite quickly
