So I rather like this game. The puzzles are mostly good, though they tend to derive too much of their difficulty from simply not knowing which side the "x" is at. The puzzles where that's easy to see are much easier than the ones where it is not. Or if that's something you are expected to be able to keep in your head it really makes it inaccessible to people with not great visualization ability (like me). One thing I really urge you to change in future games however is for the restart having to only be restarting the entire level, not just reversing the last move as most puzzle games let you do. Having to redo everything you just did just to get back to where you are is not difficult (because you know what to do), it's just annoying. It wouldn't be so bad if you could consistently reverse the mistake yourself by retracing the path, but usually if you make a mistake you can't do that, which means a lot of time is spent resetting the current part of the puzzle (and even that you can make a mistake and have to reset even there), which really takes away from the enjoyment of the game. That said, I did like the game & completed it.
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 ++
