I liked the game premise. The graphics are charming and the music as well. But, in my opinion, the gameplay need some adjustments in order to be more interesting. I have some suggestions, maybe they are worth trying out:
- instead of grabbing and dropping the weapon, the character could throw it. This way, it would be easier to hit the boss;
- The weapon shouldn't explode if I'm carrying it. That just makes the game unnecessarily difficult, I think;
- The protagonist shouldn't collide with the weapon. I kind of got stuck between a rock and the weapon, and had to move sideways;
These little improvements can add up to a better gameplay experience. But don't take my suggestions too seriously. Its just my opinion.
Well done!
