nice game the music didn't work for me for some reason.
A few notes: The enemies spotted me instantly and turned instantly it was very annoying when i would be close to an enemy almost gonna assassinate them and they would instantly turn and see me and almost kill me and when i ran away they still found me witch doesn't fit the idea of assassinating cuz they are clueless until they see and now they know exactly where i am.
Secondly the assassinating is E witch is annoying cuz i would try to run right but need to press E and it would just slow me down so instead i would suggest shift be dash and right click be assassinate so that i can run and assassinate faster, Also the assassination didn't work when i was like 2 pixels to far from the sprite so making the distance a little bigger.
lastly make the dash more satisfying. You could add particles and or sound effects, screen shakes im mad i for got to do a screen shake in mine it would have been much better, anyways the reason being you are going from a stand still to like 100mph and then stop so i want to feel that burst of energy, that fast of dash needs some power or else it feels anticlimactic and weak.
But good game, when the assassination worked it was cool i like that touch. Nice art i like it. GG! keep it up
