I bring to your court a beta-version of the game, I would really like to hear your opinion about the project, how much gameplay is complex and interesting, how responsive the controls is, how smooth is the difficulty line, and of course are there any bugs. With your advices, I hope to improve this project. Any feedback are welcome!
