If you added a timer, scoreboard and incresing difficulty, this might get interesting. As it stands this is just wonky.
The Bad:
-Character facing cursor;
-No levels, progressions or goals;
-The music DOES NOT fit the game;
-Not sure what tone you were going for;
-Really boring and unispired mechanics;
I really think if you used this as a sort of backbone and started building on it you could have a game here. Maybe have levels were you have to survive for a set ammount of time. Make characters smaller. Add different types of enemies, that you would have to face at a time. Add special abilities.
