This is an awesome game difficulty was very easy but the final level was super fun you have to focus to beat the final boss('s). It gives you a Doom vibe when playing this which is great, I found one little problem when changing the quality during the game like if you put it at modern art ( I think that´s what its called) you can't see anything maybe that's how it is or something, But I still recommend
I also made a YouTube video to show how fun it was.
