Really good concept.  I tried using the mouse, keyboard and a gamepad for input controls with mixed results.  Probably the keyboard worked best of the three.  There are some problems with the controls, and sometimes the game would hide the mouse pointer and I had difficultly getting it back.  The music fits in really well with the gameplay and the visual assets.  The concept of the game fits in perfectly with the gamejam's theme of "tiny world".  Even with its "bugs" (ha ha), this game is enjoyable.  It would be even more fun though if the input was more robust or refined, as it is hard to control the fly with either the mouse or the gamepad.  Good job!
