Changelog:

• Destructible Crates are now in. Some of them drop additional lives.
  
• Added one new enemy type. The Red Slugs are tougher to kill than the green ones.
• Changed the color of the Hearts Icons on the top left corner to red. Green was a strange color for them.
• Also removed the Timer. The player will have no time limit to finish the level. He’ll just have to kill all the creatures.

Note:

At this stage, is safe to assume that everything is still a placeholder. (The player character, crates, floor and walls definitely are. The enemies not so sure yet.)
