I like it XD
The increasing speed each time the player shoot the heart is a nice touch to increase difficulty. XD
It's hard to aim at first, but after trying many times, I got how to do it. Because the arrow will somehow do a curve, the best way to shoot is to aim it below the heart part while still far away.
Sadly the rubble and fog kinda blocking my views. There is also a time where I can't see anything. It's totally white because of fog.
But, it's still a good game XD
