What’s new:

• Added score: you get points for removing blocks and 1 point every second
• Longer combos add more health & score
• Multi-colour combos add more health & score
• Added elapsed time HUD
• Bigger blocks hitboxes for easier touch selection
• Health drain is delayed for a bit in the beginning of the level
• Added tweens for disappearing blocks
• Futile attempt at balancing. If you find the game too hard or too easy, kindly let us know!
