A fun synthesis between Sudoku and Bridges, with great accompanying visuals. Puzzle games are something I enjoy, so you bet I made it to level H1. No game-breaking bugs (that I have discovered), and a help menu in the game is a nice bonus.
Suggestions/Bugs
- Other commenters have already pointed this out, but finishing the first hard level will loop you back to the beginning.
- I wish there was a "pencil marking" mode for tiles to put possible numbers in tiles for possible combinations.
- A personal opinion, but I think a different icon/way to indicate a locked path would make it easier for players to differentiate.
- Removing a number from a tile while it is invalid (unhappy face) will not remove it until updated.
- Also pointed out by other commenters, although the game changes scale every level, it would be nice if the scale had an impact on gameplay. (i.e. "zooming in" to tiles and solving a puzzle within to remove a lock.)
