Varying brick length is a good idea but when its one long edge to edge brick that takes multiple hits to break it slows down the action to much. Also if your gameplay is all keyboard make the menues keyboard friendly. I dont like having to set down my beer to go to the next level.
Changing controls doesnt always work. I didnt bother playing beyond trying to figure what controls worked and what didnt. Make the defaults more logical or fix the options.
Most of my death come from chain stunning werewolves from offscreen. Also its annoying as hell to try finding the specific part of each level to get outside, even with the map.
