Benefits of my way of per pixel destruction:
1. Perfect performance
60 fps, 0% cpu after 450 explosions on my old PC.
60 fps, 1% cpu after 550 explosions.
In real game, I bet, 50-100 explosions will be more than enough.
2. No graphics restrictions
You will see the bottom layer through the hole in the land.
3. Perfect "physics" of my character
Instead of standard platformer my character can even slide if the incline is hard enough.
4. Only Construct 2 / Construct 3 is needed
No third party plugins or behaviors are used.
