I enjoyed the game- the concept was interesting, and probably could have worked for a more psychological game play instead of a tower-defense, but still suited the game. The atmosphere was pretty suspenseful- and the option to buy more will power added a sense of foreboding. The graphics and animation were good, the sound and music fitting.
But the gameplay, the actual programming, was poor. Far too many bugs and glitches:
The medals don't work. Having to start the game again to have another go at the final struggle. The automatic guns stuck with me, even after I started a new game, which meant I didn't have to do anything. I could never fully upgrade my ground gun, as it never stopped presenting the first upgrade. Having to click on a gun to change was annoying, a number system may have worked better for quick changes.
I am interested in seeing where the story goes- that part is what's giving this game most of it's stars, but I'm a bit worried the gameplay won't be worth it.
