It just needs more explanation in the tutorial. The game scales fine. My third game on normal level lasted over 3 hours. If anything, it might be too easy. This is a heavy math game, which I love. The huge snags can all be overcome or minimized with different strategies, that is what makes this game fun! Just practice until you can figure out combat, predicting what will happen and checking your results to see if you are right until you understand it. Do the same with the Nemisis. Once you understand, then play for real and go for you high score!
