This is something that we have seen before, this types of games are very repetitive and at this point don't offer anything new, i must admit, i wasn't expecting the best game ever but i was at least waiting for something interesting, the graphic style is very old and it shows, no shadows nor interesting colors.
If it was made by 1 person i can see how graphic can be a limitation tho, but still, no excuse for those lame animations.
The music is, the ONE song, get bad really quick and worst, is not even theme properly.
As a final though, if you are going to make a low, to none, budget game then AVOID putting ads on the menu AND loading screen, is irritating to see a bad game that also tries to squish every penny possible from ads.
