I think this is a pretty cool game. It is not without its flaws, as some of the gameplay is a bit too difficult. It also doesn't help that the graphics could be better. I still appreciate all that you've done with this game as it is fairly original. I was afraid the frog swallowing the fly was going to make me lose the game. Boy, was it satisfying to get that blue firefly!
I liked how the design was simple, but the gameplay was fairly complicated. I was not expecting that red demon thing to appear in this. I suppose you should get props for something original. It's overall a weird game, but decent. It makes me realize it's been a long time since I even saw fireflies.
