Thank you so much for the feedback. What you say is true, it is a really early progress. We just wanted to put it out as fast as we could, to put it to test and see if could be a nice idea to develop, and what we hear from you are good news. Still need to rework and updated a coulpe of things, but there are good things that we could use.
We will add your feedback to the next features and fixes we will add, I too think that the enemies might be a little too easy.
Thanks again!! :D
