Thanks for commenting, kilenc!
If the other player run away, you will actually have an easy win, because you can freely collect healing orbs from walls you destroy. You will not get damaged from the bomb if you make it explode inside a wall, so it is good to have the bomb, and you must avoid the bombless player. He can walk faster, and you can walk through walls, so you will want to strategically destroy only the walls that won't help him get to you.
The healing will get stronger the more walls you break, so don't worry if it feels insignificant in the beginning.
I ask you to play the game again, if you have the chance, and rate it if you fell like, it is very helpful! Thanks!
