Hmm could use some improvment
First of all the "IDEA" is good and concept of it all, but seems like you "RUSHED" this or something, The interest level of the game only lasts a little abit so you should think about adding more of a "FUN-FACTOR" maybe adding a mini game would be nice, or a few mini games inbetwen your own game here, its something differant and would be a nice touch to this and ofcourse bring up the quality and entertainment level aswell, and as for audio and music there was very little, if any at all, try and chose something from the audio portal, there lots of choices, and for sound/fx theres lots of websites that you can use sound/fx from just takes a little effort, Now this game could be better, but needs more effortmaybe some extra stuff added like sound and some slight new ideas with in the game but in the end it was alright.
~~THINGS TO IMPROVE ON~~
I would start off with some "MINI-GAME" option now i suggest tha idea because the interest level drops out right away so you need something to spice things up, so having a small mini bonus game within your game might improve on it. This also lacked audio and sound/fx or atleast more of it, so add more in that area.
