Hi, I played your game and its pretty impressive! I like the concept behind it! I tried some easy levels which I completed in about 2 minutes. However I was not able to complete a Medium or Hard level.
I might just be figuring out the puzzle still, but I feel like I have not quite figured out the 'rules' on how I can complete the puzzles without guessing, especially when the invisible faces appear in Medium or Hard levels, I felt like I had to guess a little to get things right? For me the best puzzles are the ones where you do not need to guess, and everything can be found based on the rules that are inherent to the puzzle. It might be a skill issue thou.
A small potential improvement could be ways to annotate! In most online puzzles, you can annotate things you know which can then help you figure out the puzzle. In your game I felt like I was kind of missing this. Two examples:
- When two faces next to each other add up to 7, I wanted to kind of place a line "|" in between them so it was clear that these two numbers should never be in the same color group.
- For two faces with the same number I also wanted to annotate something. For example, you know that two faces with the same number (for example 6) will never belong to the same color group. It would be nice to also be able to annotate something so this can be clear. I currently did this by just marking them with different colors.
Anyway, a very good concept for a puzzle game!
