Congrats on the views
Well, it must be weird having something so popular that most people don't seem to like. What I didn't like about this was how the graphics were not very good. Everything just seemed so bland. I have played so many defence games that have had better detail. Even the name needs to have more to it. It would also be a lot more enjoyable if there were sounds to accompany the enemies as they were being defeated.
I suggest you put in a lot more detail into pretty much everything. Try to work better with the shading, because it seems way off in this. Well, maybe not so much off as it looks like it took little effort to make. The music wasn't that bad. I am sorry, but there is definitley a lot of room for improvement for the creation of another game.
