In Weakness you guide a lost creature through a strange land using its powerful orb to manifest violent forces. Clear your way through all of the stages, each with a new set of characters and distinct themes. Most enemies will have a weakness to one of you weapons. You can see this weakness represented by a colored ring surrounding the character. When an enemy is hit by its weakness it will take extra damage and you will gain points. Get points to gain levels and increase your power. Enemies will sometimes drop marbles made of rare elements that will enhance the functionality of weapons when equipped.
Uh.. the video is completely black. It does have audio but there's no video, only black screen.
I opened few videos of other games on indiedb and they all work normally, so this black-screen for this video is not wrong from my end.
