Quick QoL update

Hey fellas, it's a weird feeling to actually get feedback on your project, so I've decided to make a quick update solving the worst issues.

• Coins have way bigger pick-up range
• You get free money after surviving a round
• There's no more shop timer
• Shop now let's you reroll the items for increasing price and start a new round when you're ready
• Enemies have smaller attack range
• Enemy projectiles have way smaller hitbox
• Font is now thicker for better readability
• Changed some item descriptions
• Made item names bigger
