Besides looking feeling and sounding really cool, the reflecting bullets thing is clever, and a few small design tweaks could really change it into something that could be expanded upon really nicely. For example, the 'shooting multiple enemies without lowering' mechanic is really cool, but the reward is kinda self-defeating as getting shots more accurately/ faster probably means you aren't burning as much ammo, but if you aren't doing well and need to hide away to reload more often (reloadings pretty cool btw), you'll inevitably get stuck without any way to get more ammo. Overall really cool use of the design theme.
