Exploding Boxes

This is a silly game that I made to kill time after seeing a similar version of Fruit Box posted in this website that I can't find anymore (bonus points for whoever can find it and send me a link).

Basically the same rules as Fruit Box, with a few exceptions:
- Draw a rectangle with the mouse to select boxes whose score adds up to 10
- Eliminating a square grants one point
- After eliminating square, there's a chance for remaining boxes to take damage, reducing their score
- When a box score reaches 0, it dies
- No time limit - the game ends when there are no more boxes on the screen

This game features 3 special boxes:
- Red box: explodes when reaches 0, damaging all neighboring boxes
- Green box: grows back when eliminated
- Blue box: grants 5 points when eliminated
