Hello. Thank you for your feedback with which I totally agree. As an answer, I would like to recommend you to test my new project which is more or less similar because of cubes. However, there is another gameplay and all features which you expected in Theorem - a clear visual, a key to go back and more. I cannot work on Theorem so as to add those features because I am developing other projects. I created Theorem a few years ago when I had not skill. Today I have more competence in order to work efficiently. Please take a look at my latest puzzle game - Artefaktum and you will understand what I mean. Thank you for your support which is for me really appreciable. I wish you the best. Bye ++
