while it's made the game harder to play, you could still cheese it by outrange the enemies. Also the guy at the top-most seems to have bad aim after the first one arrow. Maybe it's because I cheese by changing into the object, so it's fux up the aim.
If the difficulty is like how I got double shotted on miscalculation at first, I think it's better to make the game into stealth-centric and allowed the player to one shot the enemies instead. Maybe also reduced the range of player projectile and make the melee into much higher damage once there are more enemy types.
