That was a pretty fun little game. At the start I thought it was super difficult, but after getting used to the controls, the time limit, and the prizes (specifically making sure I kill a few "Small Bosses" for the time bonus), I was able to get the hand of things.
The gameplay was pretty simple, but also super fun. The art was very nice, and it was a fun reward to both slowly reveal more of the art as you play, but also to earn the pic for the "Gallery". Overall, pretty nice!
