Freeze powerup is one of nicest ideas in Voxatron - at least the way it's implemented. It stops rain, snow, lava animation, projectiles, even items about to time out. But it has some issues:

• Freeze stops explosions from the Boom powerup. This is nice, but monsters walking through frozen explosion don't take damage. Meanwhile player walking into frozen projectiles or monsters does take damage.
• monsters can walk through frozen player projectiles without taking damage
• Lava animation can be frozen, but lava itself doesn't freeze and still deals damage. Wouldn't it be cool if it (literally) froze solid ?

nod You are totally right :)
