The only bad thing that I can say about this game is the chained jumps, I see that you're adding impulse, when I double jump quickly that blasts me away out of the screen, overriding the y velocity when chaining jumps fixes this. I absolutely loved the perk system and how the perks could synergize to fit several playstyles I enjoyed mixing Life Link + Backstab to play extremly aggresively. It was also nice that Backstab worked on all attacks. Seeing the clones use your perks and jump around all over the level made it pretty chaotic and fun, overall this was a really awesome game.
