Glad to help! And I'll offer as much feedback as possible!
About the music, specifically: It feels like a cacophony. As in, it feel slike a lot of loud, incoherent rhythms mashed together with no cohesive glue between them. Making it less loud (or better yet - a voluem slider) would be the first step absolutely - but there's also something that you need to keep in mind: What is the pace of your game? Does this help the pace? Not help? Or worse: hinder it? Because maybe for a game about reflection (which requires some thought), a blast of cacophony isn't the best way to go about it. And I couldn't hear the SFX or anything - I'm judging purely the music I"ve heard while travelling through the levels. I actually think SFX would help a lot with game feel!
One more suggestion, if I may: That's a great excuse. Use it and abuse it: actually make it so that the stab only comes out when near the enemy, or funnier yet, when you dodge besides the enemy you instakill him with a flashy cut, just like Metal Slug! I mean it - use and abuse that excuse. Wear the inspiration on your sleeve! Heck, make the enemy placement, enemy positioning, all around metal slug!
A lot of game designers fear wearing their influence on their sleeve, but I really honestly believe it only helps your game: It's what you do different that makes it stand out, after all!
