Overall fantastic!
Like everyone else has said, this is a great game. Good replayability, fluid graphics, etc. You've done a fantastic job creating this game. 10/10 5/5
I did find one glitch though. In the pause menu when I tried to edit my key config, the prompts that appear at the bottom mix up change weapon and sheild, but goes though them just fine. (I press the keys I want in the order they appear on the list, but the promt that tells me what to do at the bottom is wrong).
Other than that, awesome job!
