It seems to have been a while since you worked on this, but some feedback:
- The pre-made puzzles feel randomly generated. I'd like to see puzzles that have an "intended solve path". For example, a puzzle that teaches a technique, or one that has deductions that nicely lead from one to the next. Or even just a puzzle that looks like something.
- When you right-click a tile to see what affects it, it would be nice if there was some animation to the purple tiles to draw the eye. It can be hard to tell exactly which tiles have changed colour, especially when the view has to zoom out to show them all.
- On that note, I'd like to not have to hold a button to see these. Physical disability can make holding buttons difficult, and this game requires a lot. Perhaps a click to toggle would be better?
- I'd also like a way to see which tiles are affected by the current tile, not just the other way around. Just as a visual reminder.
All that said, I love the ruleset. It's a very clever game. I hope you finish it.
Edited to add:
- Please wait a moment before showing the win screen, or have it out of the way somehow. I want to see the final animation as the colours fall into place. It would be satisfying!
- You have undo. What about redo? I often accidentally click undo too much, and I miss what I undid, which can be confusing.
