Ninja Blocks

It's a falling block puzzle game!
[How to play]
Move blocks up, down, left, and right to make three or more of them disappear. Each time you move them, one flame is consumed. When the flame runs out, the game is over.
Flames can be replenished by erasing six or more blocks, or by erasing them in succession.
Press and hold blocks to use a special skill.
Tap the four coloured scrolls that appear from time to time to use the respective ninjutsu.
