Ok... it's an interesting concept and i liked the visuals (i see you are a big fan of reflections) and some of the animations, but as it is, it's held back by how janky it is. The sensitivity is too high, there is no clear direction about what to do or where to go, at least on later levels, and the melee weapons don't seem to land or don't seem to do any damage beyond the first takedown on the first level, so i had to rely on the guns. And i'm not sure if it's just me, but the audio sounds muffled or simply muted. Also, a sprint button would help with later levels.
It's a good base, though, and i hope this gets improved in the future.
