Big Update 24.04.22

I've been sporadically working on the game since November last year, but decided not to upload a new version until I've got drag'n'drop working. But now that it's done, I can finally post the update. 

Changes:

• New features:
  • Drag'n'drop for modifiers.
  • Modifier limit for guns is now cost-based instead of number-based.
  • Guns can be select using keys 1-5 now.
• New modifiers:
  • "Bre" - gives your bullet a 25 percent chance to destroy an enemy bullet upon collision. Very useful when dealing with bombers, but also very rare and expensive.
  • "Aci" - applies acid status effect to enemies, which temporarily reduces their armour.
  • "Brn" - applies burning status effect, which make enemies take damage over time. Ignores armour completely.
  • "Frz" - freezes enemies, reducing their speed, firerate, etc. 
• Status effects are passed from enemies to their children.
• New enemies:
  • Mine layer - lays mines, that explode when you collide with them. They can also be triggered by bullets, or entering their detection field, in which case they will explode with a delay. Their shrapnel deals damage to enemies as well, but mine layers have a thick armour to protect from it.
• Changes: 
  • Homing bullets now prioritize enemies by angle relative to their trajectory.
  • Rebalancing
• Misc. bug fixes
