Hey there! First of all thank you so much giving our game a try. And yes, we agree with you about the difficulty spikes and so do a lot of our friend's who tried this game for us. And for that we have pushed a new version which gets rid of the tiny spikes on the edges and a few tweaks here and there in other levels for better flow of the game. This should enable a more "less pain in the ass" playthrough. :D
Once again, thanks.
