uuuuh.... it's a bit boring isnt it? i think to make it better you sould:
-have a power up bar
-have definite levels
-have a timer
-and lastly, (well, it's constructive, right?) base the clock tower on some famous ones like big ben / liver building clock tower! I think this would make it alot better! good work though i would definitly go on it again!
