Death retro feel
This sounds pretty nice actually. the way the sounds flow make it sound like it is a final boss theme in a video game that involves 8-bit graphics in it. It gives off that nice vibe like it may be your last chance to destroy the final boss since you lost all the other ones fighting your way to the boss. The only option left is to fight back against the boss.
The overall feel of the second half is that the player has just died during the final boss and is being given a second chance to come back and try one last time. Overall this turned out to be a sick and unique beat, great job.
