Simple, clean, effective. Would be a fantastic mobile game if fleshed out and polished up a bit. The clean, simple art is very appealing. Level design ideas were nice.
Not super "juicy", but I think more juice would ruin the aesthetic this is going for. This would place really high on a jam themed around "simplicity" or "clean".
I did notice a few times that the ball would move out of the hole before the next level loaded. Just a small graphical error.
Great work! I haven't really tried click and drag mechanics in a game yet, and this reminds me I need to correct that, haha.
