I`ll compare. Trying to be useful not offensive.
Let`s see...
Regular Base/Tower Defense: You get enough money to buy a tower that would probably get a rating of 5/10 at least at the beginning.
This one: You can only get a tower with a rating (I`d say this, maybe not you) of 2/10!
Regular Base/Tower Defense: There are at least 5 items with about 2 or 3 upgrades each.
This one: There are only 3 items you can use.
BUT I do enjoy the traps mode. But still...Can`t you do more? Please make a few more options and such in your next one!
