Well, I mean to be hones it was pretty funny to play! XD
At first, I thought I could just like move the owl because its shooting already by itself. But then when I realized I could like left-click, it became pretty easy. I think I could kill the enemies even when they were out of the screen.
But overall really nice cute game, since I think I read that this was your first game right? But I'm not sure anymore and if it isn't, sorry my bad XD
EDIT: well it seems I have imagined that LMAO
Buuuut, Well done!
Also, pls feel free to check out my game :P
