I played this for a while. Then I just autopiloted every day for a while. Now I forget about it for weeks at a time. My name for this game is 'Grindforever', because that's all it is.
'Unique and exciting.' Hah. The only reason I still bother is for that last badge, due to the time I've put in so far. Currently up to the aptly named Mt. Killjoy.
Decent curtain-fire game. Maybe a bit too forgiving with the defensive wave and upgrades, but that makes up for fine-tuned dodging difficulty. Good introduction to the genre.
