not bad considering its your first, i would suggest that you look at some popular TDs for some inspiration, elemental TD, for instance, is a simple game like yours but a bit of graphic updating, more towers; in general, just more options to enhance the gameplay (and unfortunatly, i do have to agree with other people about the monster versus gold ratio). Anyway, its a 3/5 for me ^^
