Tower Defense help/feedback?

Well. One small tip that bothered me in the game was the blue tower split effect. When there are multiple monsters, the tower shoots multiple bullets. The problem is, the single bullets deal the same amount of damage as these split bullets. I think that when the bullets split to hit multiple monsters, then their damage should decrease.

Also with the red tower, I think i should damage in a complete circle, not just 4 different points.

And finally, I know this may be an impossible proposition, but it would be brilliant if you could come up with an idea to make this tower defense different than the rest.

Ive played many many many tower defenses in my lifetime, and they all seem the same.

Even if the change was something really simple to ramp up the strategy, such as a multi leveled tower defense, where you cant pause the waves. Therefore you'd have to switch between levels on the game screen to build towers to defend each one. (And these towers on each level would not be able to attack monsters on other levels, though maybe a certain specialized tower would have that ability)

And another idea, perhaps instead of having an end zone where you loose health when the monsters pass it, you could have a castle (or some fortress). And then you could upgrade your castle to have defenses. And maybe this castle would be the final point for each level in the game screen. Then when your castle runs out of health from attacking monsters, youd loose the game (the attacks would be progressive, therefore the monsters would stay there until they were destroyed by either the castle or some tower.)

I think game developers these days really need to switch things up...spend more time thinking up brilliant game ideas. And i do admit, my ideas arent brilliant, but they certainly could make a normal tower defense game very interesting very quickly. And an example of the game that I think is the most brilliant ever made is "Spore". I think it is an ingenious concept coupled with very good gameplay, fantastic graphics, along with great expansion packs that actually change up the game. The galactic adventures one was probably my favorite due to its new level making mode, which is quite entertaining. Also another great game is minecraft...Which although has horrible graphics, blew quite a lot of people out of the water due to its great concept. I mean, it is quite a brilliant idea. (And pretty simple also)

Really it's all approximately opinion, however I pick Pixel Junk monsters (downloadable via PSN). It is a fairly addictive recreation that's valued at each and every penny! Meta critic gave it an eighty three out of one hundred. "Inspired by way of the standard and addictive "tower security" style, PixelJunk Monsters takes the practical truly-time technique inspiration of constructing, gaining knowledge of and base protecting and offers it in a uniquely lovely variety. With meticulously hand-drawn 2D artwork, PixelJunk Monsters recreates the appear of a traditional with crisp pics designed for top of the line viewing in Full 1080p HD."(quote from evaluation) If you could have a ps3 I might endorse this recreation. If now not? Stick with bloons!

Upgrade graphics, different title screen (green doesn't look too good), give a tower a distinct look instead of different colored circles.
