This has a decent amount of potential. It follows the same standard genre of keeping track of multiple things at once, which contains quite a few great games. However, this one, as it is now, does have a few things that could make it better. I suggest that maybe the game should get more complicated as time goes on - for instance, putting the block in the center and having arrows and squares come from places other than above you and to the right, or (playing on the title) having a few non-lethal, non-square shapes thrown in. The graphics in the base game look okay, and I like the effect that happens when you destroy an arrow or block, but the faces for the block look pretty sloppy, and the backgrounds and coin image kinda look like you got them from somewhere else. The sound could be made more engaging as well. I really hope that this helps you improve this game and make better games in the future. Don't give up hope. :)
