Bomb Type Design

Needs:
1. Invincible walls.
2. Explosions stop at invincible walls.
3. Icons for different bombs translate to how they explode.

4. Bomb modifier that can kill any type of block.

5. When holding keys while going through exit door, the next level loads right away.
    Need to prevent this and give the user more time between level transitions.
    Change between: pressed to justPressed

6. Bunnies set off the bombs and are a general pain in ass.
    Bunnies can fall in ooze and turn into monsters.
