I barely played it, but I already see that I wont like it that much.

Some core elements are tedious.
You need to pick up money, if you dont do it after a certain while the money disappears. It can be tedious, as your character will get hurt and lose money if he touches enemies so you need to wait until its clear.
The enemies move slow and there is no way to speed things up.
Its hard to say what exactly the range is of your towers is as they seem to act differently to the indicator.

I havent gotten to those stages yet, but based on other reviews there seems to be questionable balancing where elements of grinding are required and that the game is more balanced towards co op play.

Art style and music are more reminiscent of a flash game, but considering this came out originally in 2007 on a console, I guess I cant fault it too much.

Its not bad. It works. But it seems to rely on hassle work more than planning and its going to be repetitive and monotonous.
