cheap and easy.
The whole game just reaks of not trying to hard. way to easy, you can just hold down space, the upgrades pretty much make you immortal, literally, I wasn't getting hurt. gug, the graphics... yeah you know.
BUT it was weird, i was kinda having fun towards the end when there was nothing but enemies and arrows flying all over the place, that was neat, but it only lasted about 20 sec cus all the fireballs covered up the HP bars and I died.
I'd say slow down and really give it some care and love... and some better graphics please.
