Grid & window system
Grid dynamically adjusts to window size — block size, column and row count all respond to resizing
Block size presets (60/80/100px) selectable in-game
Add/remove columns and rows with dedicated buttons (with custom icons)
Window position snap presets (corners and edges)
Balls
Replaced ball lifetime with a bounce count system — balls start with 1 bounce and upgrades increase it
Ball size scales with block size
Special ball types (5 implemented)
Beach ball — larger ball with more bounces
Ghost ball — passes through blocks, damages all it crosses
Lightning ball — chains to 4 additional blocks after the initial hit
Bomb ball — grid-based explosion on impact affecting surrounding blocks
Multi ball — spawns additional balls on each hit
Dropper types (5 total)
Auto dropper — original, drops balls automatically
Laser — rotates toward targets and fires a beam
Shotgun — fires 5 pellets in a spread
Mortar — delayed arcing projectile with explosion on landing
Sniper — high-damage single target, mid-late game unlock
Upgrade tree
Full spatial grid system — upgrades placed on a 2D grid, unlocked by adjacency to purchased nodes
Block HP & economy
HP scaling uses a blocks-spawned-per-level system (grid-width-independent)
Minimum reward of $1 per block, scaling with HP
Multiple economy balance passes based on live earnings logs
