Real fun to play !
At first i was a bit confused on how the little heart monitor things worked, but then when i got it i had a blast trying to hit as many targets as possible to have enough for upgrades, and with the arrow speed and wing speed the fun is at its peek !
Just too bad that there's no music at all but hey deadlines XD other than that real solid entry that feels quite polished.
The best score i got was 23 with just 2 kills and i did it with the 2 character upgrades and no time extention upgrade.
Good job especially if it's your second game ever :)
