Surely a nice try, maybe a bit of polish around graphics (comic sans much?) and music (i just killed a blue circle, why do i still feel the void inside me? oh yeah, it's the sound of silence) would have made it feel better, although it's true that it's the mechanics that matter. The theme it's... okay; i mean it's one dot with one life. I didn't feel the winter though, sounds to me just an excuse to make a cultural reference, it's nice, but I think it's accessory to the game. After all I had fun, but you could've submitted it as a browser game and it would have been better for both you and your players.
