I love the game so far! And I can't wait to see it finished!
I was looking at your Kickstarter page and noticed that under "Features" and in one of the GUI screenshots, "Exercise" for one of the buttons is spelt incorrectly. I believe it's spelt "Exercise" rather than "Excercise". I use to have the same spelling problem with the word "Exercise" as well.
That's all I have to say for this awesome alpha demo! Can't wait for it to be released!
