The monkey mascot is a cute character design, I especially love how expressive his face gets when you hover over a very bad decision. The artstyle ties in well with the sudoku style, great job on the visuals!

I found the gameplay a bit difficult to understand, figuring out the hints was fun but most of them didn't quite make sense to me. Perhaps starting on a smaller grid would've helped with learning to understand the game? Nonetheless, it was fun to toy around with.
