Nice fun top down action game you got here, its very challanging but is still enjoyable. The music is a perfect fit, the graphic is very cute and lovely, the gameplay is smooth. Well done! The game is also surprisingly a slow and methodical action game rather than a fast past hack and slash, which is a bit unexpected.
Throwing the bone is a very risky move and I seldom do it, and resorted to using mostly melee. Not sure if this is the intended way to play but this is how I do it. The cavemen is also a bit weak in my opinion. If you got an option to throw the cavemen, at least make it double as durable. It also feels like I need to escorting the caveman too carefully and it somewhat makes the game suffers a bit. There is another issue of the scene and enemy never changed between levels, but it's probably just a polish thing.
Anyway, very well done! Keep up the good work!
