I love the music! The little frog ribbits add so much charm to it! I would suggest adding an hp bar to the flies, as it can be hard to see if you're doing any damage to them, or how much life they have left (and thus it's harder plan your hits). A little tutorial at the start of the game would be nice, too! I didn't have an opportunity to progress far into the game, as I kept dying early on. I'm not sure if the game gives you an opportunity to heal yourself, but it would certainly be useful. The artwork is pretty interesting, it reminds me of those old flash games (like Watergirl and Fireboy, for example). Gives a bit of a nostalgic feelings.
