Nicely done! I was sometimes baffled when I got hit, although nothing really hit me. Sometimes it was because the range of the weapon wasn't really great and other times I still got hit by just died enemies (in the state where they are falling). Also the "leveling" happened way too less for my taste and I wasn't fully understanding what each of the two button were doing, as the labels stated the same thing. It took me a while until I understood when and how I can "restore" those sites and I still don't know what these will do, honestly.
But it has potential and for the short amount of time you described you spent on it, it's in a good, playable state.
Well done! :)
