• better momentum mechanic added to player when jumping of moving platforms
• added floor-slide & crouch mechanic
• added momentum to player after jumping from floor-slide state
• projectile turrets
• better state logic (changing between player states)
• added another mechanic testing mode in the main menu
• better trampoline mechanics
  • (hopefully) more responsive trampolines
  • can dash into trampolines
  • trampolines record momentum better
