It's just a frogger style game, and you don't really need upgrades or traps for that. Also there was no death animation, changing background, est. And none of the enemies really matched, like you had pixelized blobs and a pixelized man and then you had not pixelized enemy knights. I'd suggest improving the graphics everywhere except for the menu, and if you keep the upgrades add some terrain or a better way to fight or something.
