I really like the idea and the game's visual mood...
... but I think the control scheme could be improved :' D, it's quite complicated to manage sharp jumps while trying to aim with the same inputs to move, and then pressing Enter (which is quite far away in my keyboard) to shoot a key.
Why not allocating the Shoot input to your mouse ? Allowing to aim freely would be up to you but it can certainly be a way to avoid a mishmash between your hands on your keyboard :' D.
Still GG for your try !
