Happy Birthday Sqroma

Sqroma has been quite an adventure, and I wanted to tweak some levels that are too difficult for the wrong reasons.

This is primarily an update to aid in the understanding of the game mechanics for new players.

World 1

Level 4 - Reduced difficulty in progressing through the level
Level 6 - Added additional visual cues to understand the path

World 2

Level 4 - Made the chain reaction less random (adjusted to be in line with the previous reaction)

World 3

Level 3 - Simplified the challenge by making the execution easier
Level 4 - Removed one of the possibility of getting stuck

Bonus World

Level 1 - Simplified a passage that was a bit too technical

That's all folks!
