I'm glad you like it :D Thank you for the feedback as well, there's a counter in the bottom center that counts down your progress but I see how that it is not very clear. I'll add some details on the game page on this regard.
Yep! It's counting down, so once you reach 0 you win :) SPOILERS: there is a boss indeed, you have to reach the last fly (when counter shows '1'), once you beat it you win.
