This may be the easiest impossible badge in terms of reaction, skill and patience. But, it's super time consuming! Good for starter to earn an impossible badge!
Sever is so lag... often stuck in loading time. The game itself is quite good. But it will be much better if upgrades is availble (only a very little bit difference between upgrades is enough). Or, add fire, ninja shadow effects, other fun effects, etc!! (3/5)
Story improved a lot than Chapter 1! Good to see that. However, same as my comment in Ch. 1, have to improve the control - Players can fully control by keyboard. And it's wonderful if the graphics and music become solid. It includes menu and transitions bewteen maps!! (3/5)
graphics are not good enough and lost interest very soon. And control can be improved, e.g. not only space bar to skip but add mouse-click. However, I like the big buttons which are easy to see, easy to understand, easy to click. Overall, not a bad game! (2/5)
How to defeat Ninga boss: Easy. 1. Upgrade Meteor to be cheaper and more damage. Flow 3-4 Meteors can kill it. 2. If the path is long enough. Let the first tower hit it once, and then cast Frency spell once it appears
