Default sound effect just wants to murder me, default BG is not great(in volume and taste) , what is ambience used for?
Just 4-5 notes of looped guitar are much better than that.
Gameplay wise is horrible. Controls are janky too be used, just stick with normal 2D format movement would have been much greater experience or give me a god damn arrow of where I am facing. Player 1 and 2 are the same picture, How in the hell am I supposed to know which one is mine and which one is my partner's in the middle of bullet hell arena? focusing junks is already hard task but man, I have to stick my eyes to my character? Just try 2D man first man, like just simple 2D top down zombie shooter from like 2000s flash game era.
