OMG loving it :D

A solid tower defense game, albeit lacking any novelty.

mTD is mechanically simple enough to be swiftly understood and beaten, yet still manages to provide a few challenges when going for expert scores.
The upgrade system trivialises the game as all maps can eventually be beaten by grinding upgrade points. A system that requires the player to improve their score on previous missions might have served the difficulty of the game better in my opinion.
Hotkeys for towers and other UI functions would have been a welcome addition.
Concerning the achievement list, "Money Maker VIII" seemed fairly excessive in its requirement as by that point any other kind of game content is long finished, resulting in a rather boring grind.

I'm a big fan of Tower defence games, your's is the best ive played today ! good work.

Simple and fun!

The only problem is that is very easy once you have the better updates, a different difficulty setting would be nice. Other than that you create a very addicting game.

simple and effective
