Shishkabobberting some flies was strangely satisfying, I enjoyed playing through it, obviously there wasn't that much to it other than that, but once I realized that you get combos by getting larger skewers of them, it became more challenging and fun.
I think you should show the score reward everytime you nail some to the wall, so people can see how they can get better & get more score. Potentially making it level based as well so that you can play in a different arena, and see it covered in skewered flies, especially if you can try to aim them in a specific direction to add them to a pre-existing skewer for more points.
It was a good and original idea, I enjoyed playing through, gave me flashbacks of the half life crossbow gun.
Great job!
Would appreciate you taking a gander at ours as well & sharing ur thoughts if you have a moment :)
