the level just starts immediately with zero time to place a turret. the third level was impossible. absolutely impossible. you can't do anything to improve your performance (like upgrading in between levels)

you absolutely have to playtest these things.

Is that all?

it was ok the controsl were a bit delayed , it could have been better really, it needs improvement in the graphic and the strategy that people need to use.

Ok overall...

Yea, it was ok...pretty basic tower defense, can never really go wrong with a good ol' tower defense... still, to start off the game you need to give at least a little time to build some turrets,and then after each individual wave of "aliens". Also maybe change the turret pricing display. Istead of saying you need 250 points to upgrade to the next level after you click on the turret, make it so you can scroll over the turret and see how much the next upgrade costs

Not thought through very well..

Sadly, the second level is almost unbeatable, making it not enjoyable enough to bother playing a second time. If there was a longer break between waves, that would've made a big difference, but there's too many factors that work against this game, which destroys its potential. A shame really.
