Well done dev on this game. This was the perfect game for me and I am so happy I came across it. It took me way too long to get through it all, but I stuck through it and got the 100%.
I honestly think this can be a great steam game! My recommendations would be to add simple tutorials for new components to the board and a definition page to the notes, as I was quickly stuck on some of the branch abbreviations, and not sure what they wanted me to do.
I had some weird stuff happening with the saving of some levels, but I assume this relates to browser-based saving.
I can actually see this game expand into a full-on game with a campaign, backstory, lore, and many more levels.
I hope that you will take this gem and expand on it as I really enjoyed the experience to the point I was losing sleep thinking of how to beat a level.
Well done once again on a brilliant game!
