major lag even on lowest quality setting with a big cache. You also can't build while the wave is paused, which is a necessity in tower defense games. The waves come too quickly late in the game and because you can't build or upgrade while the game is paused, you are screwed. Change these issues, tweak the graphics, add a better story and you might have something.
you don't explain the benefits and strengths of the various buildings and units, how am I to decide. It get monotonous and boring, really quickly. 3 out of 5
The English text is clear, it is all pixelated. The Chinese text is very clear. There are spelling errors in the English, "boombed to repeat itself..."
major lag and delay. the problem isn't the graphics or the concept, it is the gameplay. it takes forever to get anything accomplished. If you could cut the lag, make the screen slightly larger and improve the controls it would get a 4 or a 5 out of 5 as it is now, 2 out of 5
